Help me ASAP please, I need to get this done and I really can’t fail the 8th grade

What is the inverse of the function f(x) = 2x + 1?

The area (a) of a circle with a radius of r is given by the formula and its diameter (d) is given by d=2r. arrange the equations in the correct sequence to rewrite the formula for diameter in terms of the area of the circle.

Suppose that g(x)=f(x+9) which statement best compares the graph of g(x) with the graph of f(x)
