For all real numbers, x: f(x)=x^2-18 and g(x)=x^2+18. if k=f(5), what is g(k)?

G(k) = 67

f(5) = (5)^2 - 18 = 25 - 18 = 7.

g(k) = g(7)

g(7) = (7)^2 + 18 = 49 + 18 = 67.

hope this helps

Defidently don't start answering as quick as possible some teachers do say to read the hardest first but i would think the most logical answer is c carefully read the passages and i structions
