Answer:
b. is the only set of points that is a function.
Step-by-step explanation:
A relation is a function is there is not more than one y assigned to a x.
A relation relates a variable to another variable. Option a does not not this.
A set of points is a relation. A trick to figuring out if is a function is to see if all x's are different.
Let's look at b. All the x's are different there so it is a function.
Now c, we see that there are two different points with the same x so this is not a function.
Now d, we see that there are two different points with the same x so this is not a function.
Equals
That would be 0.24(0.4). First, estimate the result: 0.24 is about 1/4, and (1/4)(0.4) is about 0.1.
0.24(0.4) = 0.096 (which agrees with the estimated answer, 0.1).

Answer:
y-intercept: (0,3); x-intercept: (12,0)
Step-by-step explanation:
The y-intercept is in a line where x = 0, so to find it, you can plug in 0 for x in the equation.
y = -¹/₄(0) + 3
y = 0 + 3
y = 3
So when x = 0, y = 3, therefore the y-intercept is (0,3)
The x-intercept is when y = 0, so plug in 0 into y
0 = -¹/₄x + 3
-3 = -¹/₄x
x = 12
So when = 0, x = 12, therefore the x-intercept is (12,0)
Answer:
(0,3)
Step-by-step explanation:
y = -1/4 + 3
The intercept is (0,3)
