Question

Compare each function with the parent function. Without graphing, what are the vertex, axis of symmetry, and transformations of the parent function? y = |6x - 7| - 4

Answer 1

y = A( Bx + C ) + D

C = horizontal shift, C > 0, to the left, C < 0, to the right
D = vertical shift, D > 0, up, D < 0, down

Answer 2

So y = A(Bx + C) + D would be the parent function?

Answer 3

the parent function in this case is just
y = |x|

the other "additions" or numbers are the so-called "transformations" or shifts

Answer 4

B = shrinks or expands the graphic, B > 0, graph opens upwards, B < 0, the graph opens downward

Answer 5

Since it's absolute value, the graphic would open upwards?
|6x|

Answer 6

yes

Answer 7

I'm still confused, though. How do I find the vertex?
