To find the midpoint of a line use the midpoint formula which is M = (x1+x2/2 , y1 +y2/2) After plugging in the coordinates for your variables you should get (-1+5/2, -1+2/2) This simplifies to (2, 1/2) which is the coordinates for the middle point of the base XY.
Evaluate the given function in x=-4.
This is, replace the x in the function for -4 and find the value of g(-4).

The value of g(-4) is 32.
