$f (x) = \frac{9 + t + t^{2}}{\sqrt{t}}$

Step 1

The function $F (x)$ can be found by finding the indefinite integral of the derivative $f (x)$ .

$F (x) = \int f (x) d x$

Step 2

Set up the integral to solve.

$F (x) = \int \frac{9 + t + t^{2}}{\sqrt{t}} d x$

Step 3

Apply the constant rule.

$\frac{9 + t + t^{2}}{\sqrt{t}} x + C$

Step 4

Simplify the answer.

Step 4.1

Combine $\frac{9 + t + t^{2}}{\sqrt{t}}$ and $x$ .

$\frac{(9 + t + t^{2}) x}{\sqrt{t}} + C$

Step 4.2

Rewrite $\frac{(9 + t + t^{2}) x}{\sqrt{t}} + C$ as $\frac{9 x + t x + t^{2} x}{\sqrt{t}} + C$ .

$\frac{9 x + t x + t^{2} x}{\sqrt{t}} + C$

Step 5

The answer is the antiderivative of the function $f (x) = \frac{9 + t + t^{2}}{\sqrt{t}}$ .

$F (x) =$ $\frac{9 x + t x + t^{2} x}{\sqrt{t}} + C$
