Sorry i dont know the answer
Answer:
Step-by-step explanation:
1) Replace f(x) with y: y = 19/x^3
2) Interchange x and y: x = 19/y^3
3) Solve this result for y: xy^3 = 19, or y^3 = 19/x, or
y = ∛[19/x]
-1
4. Replace this y with the label f (x) = ∛[19/x]
2x - 3 = 15
2x = 15 + 3 = 18
x = 18/2 = 9
Therefore, the equired value of x is 9.
The answer is B, 4(x-5)(x+3)
It’s located in Quadrant III
