we have

The solution is the shaded area above the dotted line
therefore
The answer in the attached figure
<span>g(f(x)) = g(-5x+4) = 4(-5x+4) + 5 = 21-20x</span>
After striking a pair of arcs from each endpoint of a line segment, just join the intersection point of the 1st pair (above the segment) with the intersection point
of the 2nd pair (under the segment)
And this is how you construct the segment's perpendicular bisector
Answer:
it is the blue box (not teal)
64 x 7/4 is less than 64 because 7/4 > 1
Hope this helps :)
