Question

A couple quick algebra 1 questions for 50 points!


Only answer if you know the answer to all of them, Tysm!

Answer 1

C) No

D)

If we draw a vertical line, it intersects the graph at more than one point. So we can say that the image is not a function since it does not pass the vertical line test.

E) No

F)

We observe that 2 points having the same x value (-10) admit different y values,which suggests that one x value yields more than y value. So we can say the set of points do not represent a function.

Answer 2

#1

No

#2

We can see f(1) has 3 values so it's not a function as it's failed in vertical line test

#3

f(10) has two values -2 and 11

So not a function

#4

As per definition of function

• every domain has an unique range

So it's not a function
