# What is it called when a parabola touches the middle line twice?

## What is it called when a parabola touches the middle line twice?

Mathematicians call this “turning point” the VERTEX. We can make the phrase “touches the middle line twice” more formal and more precise by asking: “Does your parabola have two \$\$ x -intercepts?” Drag the blue points to create a parabola with EXACTLY ONE \$\$

## What does the phrase turning point mean?

: a point at which a significant change occurs.

Is Death of a Salesman a short story?

Death of a Salesman had its origins in a short story Miller wrote at the age of seventeen (approximately the age of the young Biff Loman), when he worked, briefly, for his father’s company. It told of an aging salesman who sells nothing, is abused by the buyers, and borrows his subway fare from the young narrator.

### How do you determine end behavior?

The end behavior of a polynomial function is the behavior of the graph of f(x) as x approaches positive infinity or negative infinity. The degree and the leading coefficient of a polynomial function determine the end behavior of the graph.

### Why was Willie fired?

It’s not just that Willy isn’t making the money he needs to make (and he hasn’t for many years), nor that he’s cracked up his car; Howard doesn’t want to Willy to represent the company any longer. He fires Willy there and then.

However, the plot, which refers to the main story in a dramatic or literary work, moves back and forth between past to present.

## What is the multiplicity of a zero?

A zero has a “multiplicity”, which refers to the number of times that its associated factor appears in the polynomial. For instance, the quadratic (x + 3)(x – 2) has the zeroes x = –3 and x = 2, each occuring once.

## How do you find the leading coefficient and end behavior?

Use the Leading Coefficient Test to determine the end behavior of the graph of the polynomial function f(x)=−x3+5x ….Leading Coefficient Test.

Case End Behavior of graph
When n is even and an is positive Graph rises to the left and right
When n is even and an is negative Graph falls to the left and right

### What is the end behavior of function H?

Function ‘h’ is a quadratic function. Since, the coefficient of the leading term (term with the highest power) is positive, parabola will open upwards. Both the ends of the parabola will be upwards (towards positive infinity). As x approaches to negative infinity, h(x) approaches to positive infinity.

### What is the main theme of Death of a Salesman?

Death of a Salesman addresses loss of identity and a man’s inability to accept change within himself and society. The play is a montage of memories, dreams, confrontations, and arguments, all of which make up the last 24 hours of Willy Loman’s life.

## What is the turning point of an equation?

What is the turning point? The turning point of a graph (marked with a blue cross on the right) is the point at which the graph “turns around”. On a positive quadratic graph (one with a positive coefficient of x 2 x^2 x2), the turning point is also the minimum point.

## What is a turning point of a graph?

A turning point is a point of the graph where the graph changes from increasing to decreasing (rising to falling) or decreasing to increasing (falling to rising). A polynomial of degree n will have at most n – 1 turning points.
