Consider the function and its inverse:
f(x) = {x-2
p(x) = a(x + 2)
The slope, a, of the inverse function is
, and the x-intercept of the inverse function is at x =

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.

The solution of the system of linear equations is b. (2,-3) because the solution is the poi (point of intersection)
