Answer:
44
Step-by-step explanation:
Parenthesis
Exponents
Multiply
Divide
Add
Subtract
First we need to do the work inside the parenthesis that are in the boxed parenthesis
3 + 1 = 4
4 * 5 = 20
Now we multiply
20 * 2 = 40
Now we add
40 + 4 = 44

Answer is y= 1/2x+1
One method is first substituting x=4,y=3 and next once again substituting x=y=2
To find the range we need to find the vertex of the parabola which is at (-b/2a , y)
-b/2a would be 2/2 = 1 ... so find the y value at x = 1
12 - 2(1) - 15 = 1-17 = -16
So the vertex is at (1,-16)
Since the parabola opens upward from that point the minimum value of the range is y = -16
The range would include the point -16 so it is actually
R = [-16,infinity)
