<h3>
Answer: Choice A</h3>
Explanation:
Each table has x = 10 in it. Plug this value into the given equation.
y = -2x+17
y = -2*10+17
y = -20+17
y = -3
The input x = 10 leads to the output y = -3. Table A shows this in the middle-most row. So that's why choice A is the answer. The other tables have x = 10 lead to y values that aren't -3 (eg: choice D has x = 10 lead to y = 12), so we can rule them out.
-8.70833333333 about but you can round to the nearest tenth (-8.7) or nearest whole number (-9)
You can factor -80 as

So, we have

The square root of a product is the product of the square roots:

Since
and
, we have

f(2) is greater than g(2) and f(-2) is less than g(-2)
