$f (t) = 1 - \frac{1}{2} t^{2}$

Step 1

Rewrite the function as an equation.

$y = 1 - \frac{1}{2} t^{2}$

Step 2

Simplify $1 - \frac{1}{2} t^{2}$ .

Step 2.1

Combine $t^{2}$ and $\frac{1}{2}$ .

$y = 1 - \frac{t^{2}}{2}$

Step 2.2

Reorder $1$ and $- \frac{t^{2}}{2}$ .

$y = - \frac{t^{2}}{2} + 1$

$y = - \frac{t^{2}}{2} + 1$

$[\begin{array}{c} x^{2} & \frac{1}{2} \\ \sqrt{π} & \int x d x \end{array}]$
