Question

Can someone help me with this? am i supposed to graph

Answer 1

Explanation:

1). a(x) = -4x + 7 If x > 1

a(8) = -4(8) + 7

= -32 + 7

= -25

2). a(x) = 2x - x² If -6 < x ≤ 1

a(1) = 2(1) - 1²

= 2 - 1

= 1

3). a(x) = |x - 8| If x ≤ -6

a(-7) = |- 7 - 8|

= |-15|

= 15

4). a(x) = 2x - x² If -6 < x ≤ 1

a(-3) = 2(-3) - (-3)²

= -6 - 9

= -15

5). a(x) = 2x - x² If -6 < x ≤ 1

`a(-(1)/(2))=2(-(1)/(2))-(-(1)/(2))^(2)`

= - 1 -
`(1)/(4)`

=
`-(5)/(4)`

6). a(x) = -4x + 7 If x > 1

`a((9)/(4))=-4((9)/(4))+7`

= -9 + 7

= -2
