Answer:
the function given
for 4 units up, just add 4 as a constant
4 units up means, every old value will now be 4 more than previous value. at x=0, y=0 in the transformed curse it should x=0 and y=4, so just add it.
for 6 units left,
each old value of y should now occur 6 units before the old value of x i.e. X=x+6
for example, the point (0,0) should occur at (-6,0) in the transformed graph,
hence,
so the final curve is
G(x) = (25 - x)/5 First lets call g(x) by its other name - y
y = (25 - x)/5 Now switch the x and y
x = (25 - y)/5 Solve for y which is now the inverse - call this
5x = 25 - y
y = 25 - 5x this is the inverse so = 25 - 5x
y = (25 - x)/5 Now switch the x and y
x = (25 - y)/5 Solve for y which is now the inverse - call this
5x = 25 - y
y = 25 - 5x this is the inverse so
