If f(x) = -5° - 4 and g(x) = -3x - 2, find (f+ g)(x).
O
A. (f+g)(0) - 5* + 3x+6
O B. (f+g)(x) = -54 - 7x-2
O c. (*+2)(x) = -5*- 3x- 6
O d. (+ g)(x) = -84-6

Answer is -5° - 3x - 6

Step-by-step explanation:

⇒ (f+g)(x) = -5° - 4 + (-3x - 2) = -5° - 4 -3x - 2 = -5° - 3x - 6

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.

what i would say the best answer is a. 40.5
