$f (x) = \frac{7 x^{2} + 7 x + 5}{\sqrt{x}}$ , $x = 3$

Step 1

Since $x = 3$ is a vertical line, the slope is undefined.

Undefined

Step 2

Since the slope of the equation $x = 3$ is undefined, there is no tangent line for $f (x) = \frac{7 x^{2} + 7 x + 5}{\sqrt{x}}$ which is parallel to $x = 3$ .

No tangent line can be found
