tangent of f(x)=5-5x^2,(5,-120)

tangent of

f (x) = 5 - 5 x^{2}, (5, - 120)

y = - 50 x + 130

Solution steps

Find the slope of

f (x) = 5 - 5 x^{2} : \frac{df ( x )}{d x} = - 10 x

EN : T i tl e G e n er a l Eq u a t i o n Sl o p e A t P o in t 2 Eq : m = - 50

Find the line with slope m=

- 50

and passing through

(5, - 120) : y = - 50 x + 130

y = - 50 x + 130
