Answer:

Answer is -32.

Step-by-step explanation:

<em>a</em>= -2

<em>b</em>=7

Expression: <em>a</em>(<em>b</em>2-<em>a</em>)

 -2(7*2--2) (Place 'a' and 'b' values)

= -2(14+2) (Solve inside the bracket)

= -28-4 (Multiply -2 with the values inside the bracket)

= -32 (ans)

7. The graph shows the height, h, in feet, of water
MariettaO [177]

The domain is talking about the "range" of the horizontal axis therefore you will be focusing on the x-intercepts.

The answer will be All non-negative real numbers less than or equal to 18

because the x-intercepts lies at 0 and 18. The answer makes sense because the furthest you can go is 18 ft and the closest you could go is 0 ft. The "all non-negative real numbers" puts a restriction on the least distance it could travel so that means that it stops at 0 ft because if you go any further, you will end up in the negatives and it clearly states "non-negative".
