tangent of f(x)=sqrt(3x+40),\at x=3

tangent of

f (x) = 3 x + 40, at x = 3

y = \frac{3}{14} x + \frac{89}{14}

Solution steps

Find the tangent point:

(3, 7)

Find the slope of

f (x) = 3 x + 40 : \frac{df ( x )}{d x} = \frac{3}{2 3 x + 40}

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{3}{14}

Find the line with slope m=

\frac{3}{14}

and passing through

(3, 7) : y = \frac{3}{14} x + \frac{89}{14}

y = \frac{3}{14} x + \frac{89}{14}
