Question

I have a few math questions (sorry i'm very behind in math)

Answer 1

Is the following relation a function?
yes
no

Answer 2

No, because if x (your domain) repeats then it is NOT a function. That would mean that there are multiple lines or curves or whatever going through the same point..

Answer 3

@xMissAlyCatx thanks (:

Answer 4

Choose the equation below that represents the line passing through the point (2, -4) with a slope of 1/2

A.) y = 1/2x + 5
B.) y = 1/2x - 3
C.) y = 1/2x - 5
D.) y = 1/2x + 3

Answer 5

The graph below shows four straight lines, P, Q, R, and S:

Which line is represented by the function f(x) = 4x – 3?
Line P
Line Q
Line R
Line S

Answer 6

for the 2nd question it would be Line S because in your equation it says "-3" which is the intersection on the y axis.. so you would find -3 intersecting with your y axis on line s

Answer 7

And the first one is C

Answer 8

The table below shows the distance d(t) in meters that an object travels in t seconds:
t seconds | d(t) (meters)
2 64
4 256
6 576
8 1024

What is the average rate of change of d(t) between 2 seconds and 6 seconds, and what does it represent?

A.)128 m/s; it represents the average speed of the object between 2 seconds and 6 seconds
B.) 80 m/s; it represents the average speed of the object between 2 seconds and 6 seconds
C.) 128 m/s; it represents the average distance traveled by the object between 2 seconds and 6 seconds
D.) 80 m/s; it represents the average distance traveled by the object between 2 seconds and 6 seconds

Answer 9

I would go with A

Answer 10

@xMissAlyCatx thanks

Answer 11

A student took a test which had 6 questions. He would score 8 points on the test if all his answers are correct. If y represents the student's score when he got x questions incorrect, which graph best represents this situation?

Answer 12

A I believe.
