Question

evaluate the function at the given values of x, if possible
f(x)= 2x-1/x^2
(a) x=2 (b) x=-1

Answer 1

a) 3/4
b)-3
did u really not kno how to do that?

Answer 2

a f(x)= 2(2)-1/(2)^2=15/4
b f(x)= 2(-1)-1/(-1)^2=-3

Answer 3

\[f(x)=\frac{2x-1}{x^2}\]
\[f(2)=\frac{2\times 2-1}{2^2}=\frac{4-1}{4}=\frac{3}{4}\]

Answer 4

\[f(-1)=\frac{2\times -1-1}{(-1)^2}=\frac{-2-1}{1}=-3\]

Answer 5

the way its written a) is 15/4 but i think he meant to write it the way satellite73 wrote it
