Step-by-step explanation:
Answer:
Step-by-step explanation:
is x ≤ -19 for inequality notation
Given: f(x) = x² + 7
Let y = x² + 7
x = y² + 7 (since the inverse is reflected about the y = x line, the coordinates are interchangeable)
y² = x - 7
y = √(x - 7)
Thus, the inverse function f^(-1)x = √(x - 7)
The solution of the equations is A) (-2,-4)
