To find the indicated outputs for the function f(x)=4x^2-5x, you need to substitute the given values of x into the function equation and simplify the expression.
1. Calculation for f(0):
Substituting x=0 into the function equation:
f(0) = 4(0)^2 - 5(0)
= 0 - 0
= 0
Therefore, f(0)=0.
2. Calculation for f(-1):
Substituting x=-1 into the function equation:
f(-1) = 4(-1)^2 - 5(-1)
= 4(1) + 5
= 4 + 5
= 9
Therefore, f(-1)=9.
3. Calculation for f(2):
Substituting x=2 into the function equation:
f(2) = 4(2)^2 - 5(2)
= 4(4) - 10
= 16 - 10
= 6
Therefore, f(2)=6.
