Answer:

1. >

2. <

Step-by-step explanation:

When a > 0, the graph opens upwards, or positively, because the way the line curves is determined by a.

When a < 0, the graph opens downwards, or negatively, for the same reason.

The fur. h is defined by the following rule.h(x) = 6*Find h(x) for each x-value in the table.X76 FSunny-2-12Explanation0000Check

muminat

Given the function:

$h(x)=6^x$

It's required to find the values of h for x = {-2, -1, 0, 1, 2}.

For x = -2:

$h(-2)=6^{-2}=\frac{1}{6^2}=\frac{1}{36}$

For x = -1:

$h(-1)=6^{-1}=\frac{1}{6^1}=\frac{1}{6}$

For x = 0:

$h(0)=6^0=1$

For x = 1:

$h(1)=6^1=6$

For x = 2:

$h(2)=6^2=36$
