Question
$$\text { Let } f(x)=\left\{\begin{aligned}x+3 & \text { if } x \geq 5 \\8 & \text { if } x<5\end{aligned}\right.$$
Step 1
Since 12 is greater than 5, we use the function \(f(x) = x + 3\). Substituting \(x = 12\) into the function, we get \(f(12) = 12 + 3 = 15\). Show more…

Let $f(x)=\left\{\begin{array}{cll}x+3 & \text { if } & x \geq 5 \\ 8 & \text { if } & x<5\end{array}\right.$ Find $f(12)-f(-12) .$ (Section 1.3, Example 6)
Given $\begin{aligned} f(x) &=\frac{1}{5}\left(2 x^{2}+3\right), \quad x \leq 1 \\ &=6-5 x, \quad 1<x<3 \\ &=x-3, \quad x \geq 3 \end{aligned}$
