Answer:
Question 2 is y = 1/2 x - 2
Question 3 is y=-2x+4
Question 4 is y = x + 3
Your other questions don't have pictures of the graph so I can't solve them sorry. Have a good day.
Answer:
f(-2) = 0
f(0) = -4
f(4) = 12
Step-by-step explanation:
Given the function f(x) = x^2 - 4, we must plug in the values substituting x for each of the answers.
f(-2) = (-2)^2 - 4
-2 times itself is a positive 4, therefore:
f(-2) = 4 - 4
f(-2) = 0
We do the same for each answer.
f(0) = (0)^2 - 4
f(0) = -4
f(4) = (4)^2 - 4
f(4) = 16 - 4
f(4) = 12
There is a possibility of 24 combinations I believe
