Find the indicated outputs for f(x)=5x^2-2x.
f(0)=
f(-1)=
f(2)=
Just plug in the numbers in parentheses () for x and perform the calculation.
For example,
f(0) = 5*0^2 - 2*0 = 0
Now you should be able to do the other two.
What do I do with the y
To find the indicated outputs for the function f(x) = 5x^2 - 2x, we simply need to substitute the given values into the function and evaluate.
1. f(0):
To find f(0), we substitute x = 0 into the function:
f(0) = 5(0)^2 - 2(0)
= 5(0) - 2(0)
= 0 - 0
= 0
Therefore, f(0) = 0.
2. f(-1):
To find f(-1), we substitute x = -1 into the function:
f(-1) = 5(-1)^2 - 2(-1)
= 5(1) - (-2)
= 5 + 2
= 7
Therefore, f(-1) = 7.
3. f(2):
To find f(2), we substitute x = 2 into the function:
f(2) = 5(2)^2 - 2(2)
= 5(4) - 4
= 20 - 4
= 16
Therefore, f(2) = 16.
