put y = 7 and x =4 and solve for c
we get 7 = 16+c or c = -9

substitute the value (4,7) to the equation, so it should be:
7=4^2+c
7=16+c
c=7-16
c=-9 (solved)

hope this helps

y=x^2+c
replace y and x with this value >(4,7)
(7)=(4)^2+c
7=16+c
c= -16+7
c= -9
The answer for c is -9

x=4
y=7
therefore,
7=4^2+c
7=16+c
-9=c
