Question

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

Answer 1

f(x)=x(x-4) as it is the only option satisfying the coordinates given (0,0),(4,0).
f(0)=0 and f(4)=0

Answer 2

Answer:

f(x)=x(x-4)

Step-by-step explanation:

f(x) = x(x-4)

To find zeroes,

Let p(x)=0

=> x(x-4)=0

=> x = 0 or x-4 = 0

=> x = 0 Or x = 4

Therefore,

0,4 are zeroes of p(x).

f(x) has two x-intercepts one at (0,0,) and (4,0)
