Step-by-step explanation:
a.) you have to substitute f(5) into the formula
f(x) = 3x^2 + 5
you do this by inserting five into your x :
f(x) = 3x^2 + 5
f(5) = 3(5^2) + 5
= 3(25) + 5
= 75 + 5
f(5) = 80
b.) to solve for g(5) ,, you do the exact same but with the formulae g(x) = 11x - 10
g(x) = 11x - 10
g(5) = 11(5) - 10
= 55 - 10
g(5) = 45
. we can see that f(5) is the greater quantity ,, furthermore it is greater by 35 . =
f(5) = 80 g(5) = 45
80 - 45
= 35
