Question

Evaluate the function at the specified values of the independent variable and simplify

Answer 1

f(x)= sqrt(x+8)+2
(a) f(-8) (b) f(1) (c) f(x-8)

Answer 2

looks like a simple plug in
for A) sub in -8 for x and just simplify

Answer 3

What about b and C?
Also is this right
f(x) = sqrt(x+8) + 2
f(-8) = sqrt(-8+8) + 2
f(-8) = sqrt(0) + 2
f(-8) = 2

Answer 4

thats correct
b)\[f(1)=\sqrt{1+8}+2=\sqrt{9}+2=3+2=5\]
c)\[f(x-8)=\sqrt{x-8+8}+2=\sqrt{x}+2=x+2\]
