Answer:

D. the graph of g(x) is shifted 3 united left and 4 units up.

Step-by-step explanation:

When a change is made inside the parenthesis to the input, the function shifts left and right. Addition shifts it left while subtraction shifts it to the right. Here it is translated three units to the left. Adding or subtracting a number outside the parenthesis will slide the function up and down. Here it is shifted 4 units up.

Example:    f(x) = x            f(x+3)+4 = x_{n-3}+4

                   f(3) = 3                 x+3 = 3

                                               x+3-3 = 3-3

                                             x=0 and f(0) = 0

                                                 So f(0) +4 = 0+4 =4

What is the slope of the line passing through the points (-3,4) and (4,-1)
Serhud [2]

Answer:

slope = - \frac{5}{7}

Step-by-step explanation:

Calculate the slope m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 3, 4) and (x₂, y₂ ) = (4, - 1)

m = \frac{-1-4}{4+3} = - \frac{5}{7}
