Question

find the indicated outputs for f(x) = 5xto second power - 2x

f(0) = --?
f(-1) = --?
f(2) = --?

Answer 1

find the indicated outputs for f(x) = 5xto second power - 2x

f(0) = --?
f(-1) = --?
f(2) = --?

Answer 2

\[f(x)=5x^2-2x\]
\[f(o)=0\]
\[f(-1)=5(-1)^2-2\times -1=5+2=7\]

Answer 3

\[f(2)=5(2)^2-2\times 5=5\times 4-4=20-4=16\]
