If f(x)=3^x+10x and g(x)=4x-2, find (f+g)(x)

Hi there!

First we need to remember the following.


Now substitute both of the formulas.


Work out the parenthesis.


And finally collect terms.

Hi there!

(f + g)(x) = f(x) + g(x)

(f + g)(x) = (3ˣ + 10x) + (4x - 2)

(f + g)(x) = 3ˣ + 10x + 4x - 2

(f + g)(x) = 3ˣ + 14x - 2

~ Hope it helps!

The answer is option c.
