Question

A function is shown: f(x) = 36x2 − 1.

Answer 1

Answer:

The equivalent function: $f(x)=(6x+1)(6x-1)$

Step-by-step explanation:

The x-intercepts of the given function on the graph can be obtained by equating the function to zero.

This is because on the x-axis, the y-coordinate is zero.

$36x^{2} -1=0\\36x^{2} =1\\x=\frac{1}{6},-\frac{1}{6}$

The function that has the same x-intercepts on the graph from the given options is:

$f(x)=(6x+1)(6x-1)$

Alternate Method:

The answer can also be obtained by factorizing the question.

Answer 2

Answer:

D

Step-by-step explanation:

f(x) = (6x+1)(6x-1)
