Answer:
B) Function 1, because the slope is 4 and the slope of function 2 is 2.
Step-by-step explanation:
Function 1 is in slope-intercept form, which is
y = mx+b, where m is the slope and b is the y-intercept.
This means the slope of function 1 is 4.
The slope of function 2 is given by the formula
Using our two points for function 2, we have
m = (10-6)/(3-1) = 4/2 = 2
This means the slope of function 1 is greater.

Answer:
D
Step-by-step explanation:
Try to remember this formula.
Where a is the vertical multiplier, b is the horizontal multiplier, c is the x coordinate of the vertex, and d is the y coordinate of the vertex.
Since the vertex on the graph is (2,3), c and d have to be 2 and 3.
Also, there are no vertical/horizontal stretches so the a and b values stay at 1.
The final equation would come out to
