Find the equation of the tangent line to the curve at the given point. 5x2+ y2 + 4xy=
1 at (0,1)
A. Y= –2x - 1
B. y = 2x - 1
C. y = – 2x + 1
D. Y = 2x +1

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !

2x^2+5x+17

your welcome. : )
