Evaluate $f(-2)$, $f(-1)$, $f(0)$, $f(1)$, and $f(5)$ for the piecewise-defined function. $f(x) = \begin{cases} 3x^2 & \text{if } x < 0\\ 2x + 1 & \text{if } x \ge 0 \end{cases}$

Step 1
So, we substitute -2 into the first part of the function: f(-2) = 13(-2)^2 = 13(4) = 52 Show more…

Evaluate the piecewise defined function at the indicated values. $$ \begin{array}{ll}{f(x)=\left\{\begin{array}{ll}{3 x} & {\text { if } x<0} \\ {x+1} & {\text { if } 0 \leq x \leq 2} \\ {(x-2)^{2}} & {\text { if } x>2} \\ {(x-2)^{2}} & {\text { if } x>2}\end{array}\right.} \\ {f(-5), f(0), f(1), f(2), f(5)}\end{array} $$

What Is a Function?
Evaluate the piecewise defined function at the indicated values. $$ \begin{array}{ll}{f(x)=\left\{\begin{array}{ll}{5} & {\text { if } x \leq 2} \\ {2 x-3} & {\text { if } x>2}\end{array}\right.} \\ {f(-3), f(0), f(2),} & {f(3), f(5)}\end{array} $$
Evaluate $f(-3), f(0)$, and $f(2)$ for the piecewise defined function. Then sketch the graph of the function. $$ f(x)=\left\{\begin{array}{ll} 5 & \text { if } x<2 \\ \frac{1}{2} x-3 & \text { if } x \geqslant 2 \end{array}\right. $$
