5-37.

For each of the following functions, describe how different values of $t$ will affect the graph.

$y = 3 ( x - t ) ^ { 2 } + 2$
Hint (a):
Notice that $t$ is inside of the parentheses with $x$ .
Answer (a):
Horizontal shift right if $t > 0$
Horizontal shift left if $t < 0$

$y = t \left| x - 3 \right| + 4$
Hint (b):
Notice that $t$ is "being multiplied".
Answer (b):
Vertical stretch for $\left| t \right| > 1$
Vertical compression for $\left| t \right| < 1$
Reflection if $t < 0$
