y = 4 Answer B
Answer:
See below
Step-by-step explanation:
Question 2:
A relation is a function if every different x-value has a y-value. Since this relation has two outputs for x = 4 (1 and 9), it is NOT a function.
Question 3:
Plug the three points listed (-1, 0, 1) into the function and get their outputs. This will be the range.
f(x) = 2x + 4
Plug in -1.
f(-1) = 2(-1) + 4
f(-1) = -2 + 4
f(-1) = 2
f(x) = 2x + 4
Plug in 0.
f(0) = 2(0) + 4
f(0) = 4
f(x) = 2x + 4
Plug in 1.
f(1) = 2(1) + 4
f(1) = 2 + 4
f(1) = 6
This makes the range {2, 4, 6}.
