Answer:
f(x)= x2 - 2x + 3
0=3
x = ¤
Step-by-step explanation:
f(x) = -2x +19
0=-2x +19
2x=19
x =19/2
x= 9,1/2
x=9,5
Answer:
21x + 27
Step-by-step explanation:
Answer:
Sorry can't see on school computer :(
Step-by-step explanation:
A reasonable domain and range is the set of values that exist for the function. The sets that are not reasonable are not considered domain and range. For instance, f(x) = 15√(x - 3)
The reasonable domain is {x | R, x ≥ 3} since you can't have negative value inside the radicand.
The reasonable range is {f(x) | R, f(x) ≥ 0} since the minimum value is 0 [Noting that x = 3 gives f(3) = 15√(3 - 3) = 15√0 = 0]
