Question

P(s) = s³ + 10s
f(s) = 6s - 3
Find p(2)-f(2)

Answer 1

19

Explanation:

We are given the following two functions of s

`p(s) = s^3 + 10s\\f(s) = 6s - 3\\\\\text{To find p(2) substitute 2 for s in p(s)}\\p(2) = (2)^3 + 10(2) = 8 + 20 = 28\\\\`

`\text{To find f(2) substitute 2 for s in f(s)}\\f(2) = 6(2) - 3= 12 - 3= 9\\`

`p(2) - f(2) = 28 - 9 = 19`
