Answer:
Range : {11,27,43,59}
Step-by-step explanation:
Given:
f(x) = 4x - 1
Domain : {3,7,11,15}
f(3) = 4(3) -1 = 11
f(7) = 4(7) -1 = 27
f(11) = 4(11) -1 = 43
f(15) = 4(15) -1 = 59
hence Range : {11,27,43,59}
Corresponding points are reflected over the y=x line, or otherwise, the coordinate values are switched!
So if the log function has point (1,2) on it, the exp function will have (2,1)

Answer:
2(28)=23+x
Step-by-step explanation:
There are 28 students and each student needs two brownies. You have to multiply 28 by 2 so you will have to total number on one side.
On the other you need to have the number of brownies you have at the moment and x for the number you need to bake. You want to add them because you will need to put those numbers together to get the number on the opposite side.
28x2=56 so 56=23+x. Subtract the 23 from both sides to get 33=x. x=33
To check plug 33 into x to get 2(28)=23+33. 56=23+33. 56=56
you need 33 more brownies.
So the equation would be 2(28)=23+x.
Hope that helps.
