Question

Let f(x) = 5x – 2 and g(x) = 9x + 12. Find f(x) + g(x).

Answer 1

Answer:

f(x) + g(x) = 14x + 10

Step-by-step explanation:

f(x) = 5x – 2 & g(x) = 9x + 12

f(x) + g(x)

5x – 2 + 9x + 12

14x + 10

Answer 2

Answer:

14x + 10

Step-by-step explanation:

Step 1: Define

f(x) = 5x - 2

g(x) = 9x + 12

Step 2: Find f(x) + g(x)

5x - 2 + 9x + 12

14x - 2 + 12

14x + 10
