So we have v(w) = 2w - 1
Now we make the following change: w ---> w +3.
So we change every "w" into a "w+3" as follows:
v(w) = 2w - 1 --------> v(w+3) = 2*(w+3) - 1
Let's solve this.
2*(w+3) - 1
2*w + 2*3 - 1
2w + 6 - 1
2w + 5
So
v(w+3) = 2w + 5
To find the coordinates of the vertex, you use the formula x=-b/(2a)
in this case, a is 6, b is 5
x=-5/12
Next, find out the value of y when x is -5/12
y= 6(-5/12)^2 +5(-5/12) -6
y=-23/8
so the vertex is at (-5/12, -23/8)
Please double check the calculation by yourself

Answer:
No, 7a does not equal 56. If a = 7, then 7a would equal 7 * 7. And, 7 * 7 = 49.
