Question

Which function has two x-intercepts, one at (0,0) and one at (4,0)?

Answer 1

Answer:

$f(x)=x(x-4)$

Step-by-step explanation:

Given: Function has two x-intercepts, one at (0,0) and one at (4,0)

To choose: the correct option

Solution:

x-intercepts of are the points whose x-coordinate is 0.

Consider $f(x)=x(x-4)$

Put $x=0$

$f(0)=0(0-4)=0$

Put $x=4$

$f(4)=4(4-4)=0$

So, the function $f(x)=x(x-4)$ has two x-intercepts, one at (0,0) and one at (4,0).
