For the curve y = 15 + 6x - x2: a) Work out the value of y when x = 3.
b) Work out the value of dy/dx when x= 3.
c) Thus find the equation of tangent to the curve at the point where x = 3.

if you use photomath right away it will give you the answer not like this app that you have to wait for people.

fist on the left goes with the third on the right. second on the left goes with the fourth on the right. third on the left goes with the second on the right. the fourth on the left goes with first on the right
