just multiply the two functions and evaluate at x=7
How do you multiply them?
(x-3) * (x^4 + 25). Is this what you are suppose to get when you multiply them?\[x ^{5}-3x ^{4}+25x-75\]

Other answers:

you forgot the square root over the x-3
(g*k)(7) is the same as g(7) * k(7)
I squared the both equations so I can get rid of the square root.
find g(7) and k(7). Then multiply those results
squaring x^2 + 5 does not give x^4 + 25 also, squaring can only be done when you square both sides of an equation
Would the answer be 216 then?
Oh I keep forgetting some steps. But I got the answer doing what you said.
it's not 216
x^2 + 5 = 7^2 + 5 = 49 + 5 = 54 sqrt(x - 3) = sqrt(7 - 3) = sqrt(4) = 2 54 * 2 = 108 I forgot to sqrt the 4 earlier.
108 is correct
Thanks!
no problem
