Question

Need help with a set of problems please:

If f(x) = x2 + 7, what is the equation for f–1(x)?
Let f(x) = -2x - 7 and g(x) = -4x + 6. Find (fog)(-5)
The graph of y = √x is shifted 3 units down and 2 units right. Which equation represents the new graph?
If the parent function is √x, describe the translation of the function √x+7.
Let f(x) = -4x - 2 and g(x) = 5x - 6. Find f o g and state its domain.
Let f(x) = 3x - 6 and g(x) = x - 2. Find g/f and state its domain.
Let f(x) = -4x + 7 and g(x) = 2x - 6. Find (g o f) (1).
Let f(x) = -4x + 7 and g(x) = 2x - 6. Find (f o g) (1).

Answer 1

Lets start from the first problem,
\(\large\color{slate}{ f(x) = x^2 + 7 }\) and you need to find the \(\large\color{slate}{ f^{-1}(x) }\)
