1.1 intro to functions\nscore: 8/10 6/8 answered\nquestion 7\nfor the function $f(x)=x^2 - 36$, evaluate $f(x+h)$.\n$f(x+h)=$\nquestion help: video message instructor
Answer
Explanation:
Step1: Substitute $x+h$ for $x$
$f(x+h) = (x+h)^2 - 36$
Step2: Expand the squared binomial
$(x+h)^2 = x^2 + 2xh + h^2$
Step3: Substitute back and simplify
$f(x+h) = x^2 + 2xh + h^2 - 36$
Answer:
$x^2 + 2xh + h^2 - 36$
