Question

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

Answer 1

Answer:

Step-by-step 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

    $a(-\frac{1}{2})=2(-\frac{1}{2})-(-\frac{1}{2})^{2}$

               = - 1 - $\frac{1}{4}$

               = $-\frac{5}{4}$

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

    $a(\frac{9}{4})=-4(\frac{9}{4})+7$

            = -9 + 7

            = -2
