Question

If function f has zeros at -3 and 4, which graph could represent function f?

Answer 1

The answer is A the points are (0,-3) and (0,4)

Answer 2

A

Explanation:

f has zero means that f(x)=0

if f(x)=0 we have to look intersection point or points in the graph on the x-axis.

for A

y=0

x=-3, x=4

for B

y=0

x=-4, x=3

for C

y=0

x=-4, x=-3

for D

y=0

x=3, x=4
