Question

Determine f(a+h) for f(x) = 2x^3

Answer 1

f(a+h) = 2(a+h)³ = 2a³+6a²b+6ab²+2b³

Explanation:

f(x) = 2x³

f(a+h) = 2(a+h)³

The question is not clear on how the answer should be presented.. but if you need to expand and simplify.......then:

f(a+h)

= 2(a³+3a²b+3ab²+b³)

= 2a³+6a²b+6ab²+2b³
