Answer:
Equation:
when n = 4
Step-by-step explanation:
Given
Direct Variation: P ∝ n
When n = 15, P = 150
Required
Determine the equation
Her earnings if she sold 4 necklaces
P ∝ n
Convert variation to equation
When P = 150, n = 15 (Substitute these values in the given equation)
Divide both sides by 15
Substitute k = 10 in
------- Equation that relates P and n
When she sold 4 necklaces, n = 4
Substitute n = 4 in the formula above
The function is a cube root function
The function end behavior is:
The equation of the function is given as:
To determine the end behavior, we plot the graph of the function f(x).
From the attached graph of the function, we can see that:
As x approaches infinity, the function f(x) approaches infinity, and vice versa
Hence, the function end behavior is:
