Step-by-step explanation:
-5+4=-1
-3+4=1
0+4=4
4+4=8
F=-50 as multiplying it by -6.2 would give you a positive 310
O.533333333,basically 8 divide by 15
(x - 2)^2 will always be positive and will have a minimum value of 0
so f(x) will have minimum of 2
Range is [2,∞)
Substitute the values in the expression
b-a=3-2=1
answer b-a=1
