if f(x)= x+2, find the equation of the function F obtained by stretching the function f vertically by a factor of 2 and compressing the function horizontally by a factor of 2, followed by a translation of 1/2 horizontally and -3 vertically.
the equation is: -x^2 - 6x - 7
what happens to the points (0,2) and (-1,1) under the transformation? i don't know what to do/how to find the answer
