Which of the following describes how to translate the graph y = |x| to obtain the graph of y = |x| - 4?
2 answers:
Answer:
4 units down
Step-by-step explanation:
Translations are transformations that change the position of the graph of a function. The general form of the graph of a function is moved up, down, right or left
Given a function:
A vertical translation can be expressed as:
Where:
So:
It's a vertical translation 4 units down. You can corroborate checking the picture I attached you and evaluating the function at x=0

Answer:
undefined
Step-by-step explanation:
To find the slope of the line between two points, use the slope formula .
and
represent the x and y values of one point the line passes through, and
and
represent the x and y values of another point the line also passes through. Therefore, use the x and y values of the points (0,3) and (0,4) to find the slope. Substitute them into the formula in the right order:
However, we can't divide 1 by 0. Therefore, the slope is undefined. (You could also graph the points to see that they form a vertical line, and all vertical lines have an undefined slope.)
