tangent of f(x)=(8x)/(x+7),(2,1.7777700000000…)

tangent of

f (x) = \frac{8 x}{x + 7}, (2, 1.7777700000000 \dots)

y = \frac{56}{81} x + 0.39505 \dots

Solution steps

Find the slope of

f (x) = \frac{8 x}{x + 7} : \frac{df ( x )}{d x} = \frac{56}{( x + 7 ) ^{2}}

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 = \frac{56}{81}

Find the line with slope m=

\frac{56}{81}

and passing through

(2, 1.77777 \dots) : y = \frac{56}{81} x + 0.39505 \dots

y = \frac{56}{81} x + 0.39505 \dots

y = 5^{x - 3}, (3, 1)

f (x) = x^{3} - 2 x^{2} + x + 1

\int_{- 2}^{- 1} \frac{1}{( x - 1 ) ^{3}} d x

7 x + 12, 0, 10

\frac{1}{s ^{3} ( s + 2 )}
