Question

How can you tell the zeros of this function by looking at the graph? What are the zeros of the function?

A) Zeros occur at the minimum value. On this graph the zero is -10.
B) Zeros occur where the graph intercepts the y-axis. On this graph the only zero is -9.
C) Zeros occur where the graph intercepts the x-axis. On this graph the zeros are -1, 1, and 3.
D) Zeros occur where the graph intercepts the x-axis. On this graph the zeros are -1, 0, 1, and 3.

Answer 1

C

Explanation:

The zeros are the points where the graph intersects the x- axis.

In this case that is when x = - 1, x = 1 and x = 3

The zeros are - 1, 1, 3 → C

Answer 2

C.Zeroes occur where the graph intercept the x- axis. On this graph the zeroes are -1,1 and 3.

Explanation:

We are given that a graph of function.

We have to tell how can find the zeroes of function and what are the zeroes of the function.

Zeroes of function:Zeroes are the values of x where the graph cut the x- axis.

Zeroes are the x- intercept of graph.

In given graph , the graph cut the x- axis at x=-1,1 and 3.

Answer:C.Zeroes occur where the graph intercept the x- axis. On this graph the zeroes are -1,1 and 3.
