Answer:
3^x + 10x+2x-4
Step-by-step explanation:
f(x) = 3^x + 10x and g(x) = 2x - 4
(f + g)(x)= 3^x + 10x+2x-4

Answer:
f⁻¹(x) = (1/2)x +5
Step-by-step explanation:
In y = f(x), swap the variables, then solve for y. The expression you get is f⁻¹(x).
... y = 2x -10
... x = 2y -10 . . . . . . swapped variables
... x +10 = 2y . . . . . add 10
... (1/2)x + 5 = y . . . . divide by 2
... f⁻¹(x) = (1/2)x + 5 . . . . . . rewrite using function notation
