Question

Perform the indicated operation

g(a) = 3a + 1

f(a) = a3 + 2

Find g(a) + f(a)

Answer 1

if f(a) is
\[ f(a)= a^3 + 2 \]
you should use ^ and write it like this
f(a) = a^3 + 2

but to answer the question, write down the "right hand side" of the first equation, put a plus sign and then write down the right hand side of the second equation.

Answer 2

then combine "like terms", and write it standard order (terms with the biggest exponent are written first)
