Answer:
a) f(-1) = 1
b) f(0) = 6
c) f(2) = 8
Step-by-step explanation:
If x is lesser than 0, we have that:
f(x) = 4x + 5
Otherwhise
f(x) = x + 6
(a) f(-1)
Here x = -1.
-1 is lesser than 0
Then
f(x) = 4x + 5
f(-1) = 4*(-1) + 5 = -4 + 5 = 1
(b) f(0)
Here x = 0
When x equals 0
f(x) = x + 6
Then
f(0) = 0 + 6 = 6
(c) f(2)
Here x = 2
When x = 2
f(x) = x + 6
Then
f(2) = 2 + 6 = 8

Step-by-step explanation:
I think you're having trouble because the equation you wrote for 8a has a slight typo.
The question says that the length is 9 less than twice the width. Your equation states the length is 9 times the width minus 2. So the length actually equals 2w – 9, meaning that w(2w – 9) = 180
Hope this helps! If you're still having trouble, let me know :)
