For the first question on the screenshot, you need to put this same exact order as I put it.
A D B C
Now the second question
A = 3 units
B = 4 units
C = 4 units
D = 3 units
Answer: (a) -7 (b)
(c)
(d) 4
Step-by-step explanation:
A) f(x) = 2x - 3 when x is between -5 and -2 (including -5 and -2)
B) f(x) = x² when x is between -2 and 2 (including 2)
C)
when x is between 2 and 5 (including 5)
a) Equation A includes x = -2
f(x) = 2x - 3
f(-2) = 2(-2) - 3
= -4 - 3
= -7
b) Equation B includes x = 
f(x) = x²


c) Equation C includes x = 4




d) Try each equation to see if x falls within the values given.
A) f(x) = 2x - 3
-2.5 = 2x - 3
0.5 = 2x
0.25 = x NOT VALID since x should be between -5 and -2
B) f(x) = x²
-2.5 = x²
NOT VALID since x cannot be an imaginary number
C) 



VALID since x is between 2 and 5
