SOLUTION: okay the question is if f(x)=x squared+3x-2 and it says that F(5v) Im supposed to find each value This is what I got and Im pretty sure it's wrong 5v squared+13v=18v to the 3rd

Question 125980: okay the question is if f(x)=x squared+3x-2 and it says that F(5v) Im supposed to find each value
This is what I got and Im pretty sure it's wrong
5v squared+13v=18v to the 3rd power
Thanks for any and all help

You can put this solution on YOUR website!
If f%28x%29+=+x%5E2%2B3x-2, findf%285v%29 You substitute 5v for x in the equation.
f%285v%29+=+%285v%29%5E2%2B3%285v%29-2
f%285v%29+=+25v%5E2%2B15v-2
