Answer:
{12,15}
Step-by-step explanation:
Given the function f(x) = x+5, if the range of the function is {7,9}, the domain of the function is derived by simply finding the value of the function at each end point.
At endpoint x = 7,
f(7) = 7+5
f(7) = 12
At endpoint x = 9
f(9) = 9+5
f(9) = 14.
The function domain is therefore at {12,14}
Answer:
1=4(2)-7
Step-by-step explanation:
y=mx+b
b=where it crosses the y-axis
m=slope
1=4(2)-7
Answer: the anwser is C
Step-by-step explanation:
