Question

What is the zero of the following function?

A. x = -5
B. x = -1
C. x = 1
D. x = 5

Answer 1

I think the correct answer would be letter C. x=1

Answer 2

The correct option is A.

Explanation:

To find the zeroes of a function, we equate the function equals to 0, i.e., f(x)=0 or y=0. It means the value of the function is 0 at its zero.

At x-axis the value of y is 0.

If a function is defined by a graph, then the x-intercepts represents its zeroes.

From the given graph it is clear that the x-intercept of the function is at x=-5. So, the value x=-5 is a zero of the function.

Therefore the correct option is A.
