An automotive mechanic charges a flat diagnostic fee of $25 to diagnose the problem in a vehicle and $65 per hour for labor to fix it. if the mechanic increases his diagnostic fee to $30, what kind of transformation is this to the graph of the total repair bill?

d

step-by-step explanation:

by observation, we can see that the the graph is simply the graph of y = |x| that has been shifted 4 units downwards and 3 units to the left.

we can recognize in choice d :

y = | x + 3 |   - 4 (rewriting in general form)

y = | x - (- 3) |   - 4

the "-4 " term means   that the graph has been shifted by 4 units in the negative y direction

the "-3 " term means   that the graph has been shifted by 3 units in the negative x direction

this matches our observation of the graph described above.

step-by-step explanation: you take each of the numbers and divide by the amount then you take the range
