Answer:

(1,5) and (5.25, 3.94)

Step-by-step explanation:

Basically look for the intersection points of these two functions by setting them equal to each other.

-x^2 + 6x = 21/4 - x/4

-x^2 + (25/4)x - 21/4 = 0

x = 1 and x = 21/4

Plug these points back to any of the two original equations, you will get

(1,5) and (21/4, 63/16)

or (1,5) and (5.25, 3.94)
