Explanation:

f(x) = 9 - 2|x + 2|

When x = 7, f(-7) = 9 - 2|(-7) + 2|

= 9 - 2|(-5)|

= 9 - 2(5)

= 9 - 10

= -1.

Answer:

-1

Explanation:

Put -7 where x is and do the arithmetic.

f(-7) = 9 -2|-7+2|

= 9 -2|-5| = 9 -2·5 = 9 -10

f(-7) = -1

If f(x) = 9-2 |x+2|, find f(-7). -15 -1 1 19-example-1
