Question

Which is true about the graphs of the two functions f(x) = (x-4)(x-9)and f(x)=(x-6)^2

Answer 1

They have the same range.
They have the same vertex.
They have the same y-intercept.
They have the same axis of symmetry

Answer 2

Answer 3

Hmmmm

Answer 4

The y intercept is the easiest to check. Just let \(x=0\).

Answer 5

What Does That Mean

Answer 6

\[
(x-4)(x-9)\bigg|^{x=0} = (0-4)(0-9) = -4\times -9 = 36
\]and \[
(x-6)^2\bigg|^{x=0} = (0-6)^2=-6\times -6 = 36
\]

Answer 7

They both have a \(y\) intercept at \(36\).

Answer 8

So They Share The Same Y Intercept

Answer 9

You have to try a bit, dude.

Answer 10

iAM

Answer 11

Yeah, they share the same y intercept

Answer 12

What is the axis of symmetry of the function f(x) =-(x+9)(x-21)
