3. Grades in a class are weighed as follows: 30% homework, 30% tests, 20% quizzes, 20% participation. Suppose that a student has a 92 homework grade, 88 quiz grade, and 100 participation grade. What must their test average to have
an A in the course?
4. Using the information from above, suppose that the same student has a 87,95, and 72 as their test grades so far.
What must they get on their next test in order to have a 93 overall in the course?

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.

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
