What is the y- intercept of the quadratic function f(x)=(x-6)(x-2)?

The y-intercept of the quadratic function f(x) is 12.

Step-by-step explanation:

The given function is

At y-axis the value of x is 0.

Substitute x=0 in the given function to find the y-intercept of the function.

On simplification, we get

The graph of function intersect y-axis at (0,12).

Therefore the y-intercept of the quadratic function f(x) is 12.

i think that you should ask google for the answer to that problem because if we don't know it google does

pi x^2

step-by-step explanation:

pi times x squared
