Find the indicated outputs for f(x) = 2x²-4x
f(0)= ____?
f(-1) =____?
f(2) =____?
f(0) = 2(0)^2 - 4(0)
= 0*0
= 0
f(-1) = 2(-1)^2 - 4(-1)
= 2(1) + 4
= 2 + 4
= 6
now you try f(2) the same way.
Reiny
I'm still lost
i only got so far.
f(2)=2(2)^2-4(2)
=2(2) from their on i'm lost please help
To find the indicated outputs for the given function f(x) = 2x² - 4x, we need to substitute the given values of x into the function and evaluate it.
For f(0), we substitute x = 0 into the function:
f(0) = 2(0)² - 4(0)
= 0 - 0
= 0
So, f(0) = 0.
For f(-1), we substitute x = -1 into the function:
f(-1) = 2(-1)² - 4(-1)
= 2(1) + 4
= 2 + 4
= 6
So, f(-1) = 6.
For f(2), we substitute x = 2 into the function:
f(2) = 2(2)² - 4(2)
= 2(4) - 8
= 8 - 8
= 0
So, f(2) = 0.
Therefore, the indicated outputs for f(x) = 2x² - 4x are:
f(0) = 0
f(-1) = 6
f(2) = 0.
