Question 478817: I can not figure out how to get rid of my denominator...do i multiply by the reciprocal or square root or something else...I am struggling to even begin. I sub in (1) for all X-values correct?
Find the value of the function:
f(1) when f(x)=(x^2-5)/ (x+3)
Please show how this is done.
Thanks!

You can put this solution on YOUR website!
f(1) when f(x)=(x^2-5)/ (x+3)
-----------
Sub 1 for x
f(1) = (1-5)/(1+3) = -4/4 = -1
