Question

How would I solve these Problems?

Answer 1

The range of the relation below is

x y
−3 −8
3 −8
6 4
10 2

{−3, 3, 6, 10}

{−8, −8, 4, 2}

{−8, 2, 4}

No range exists.


and:

Which of the following does not represent a function?

x −12 −5 11 14 17
y −5 −2 −2 8 34

x −10 1 3 8 10
y −2 2 7 8 10

x 5 10 10 12 18
y 1 4 22 5 4

x 4 5 6 8 10
y 4 −4 12 −8 6

Which of the following does not represent a function?

graph of a negative parabola oriented about the y axis with y intercept at positive 6

graph of an absolute value function oriented about the y axis

graph of an ellipse with x intercepts negative 8 and positive 8

graph of a negative parabola oriented about the y axis with y intercept at positive 6

and :

Is the following relation a function?

two ovals, one labeled x and the other labeled y.
The −2 in the x oval is pointing to the 8 in the y oval, the 0 in x is pointing to 1 in y,
5 in x pointing to 3 in y, and 7 in x pointing to 5 in y

and:

Answer 2

problem (5) g(-4)=16+5=21
problem (6) f(4)=2*4^2 -30=16-30=-14

Answer 3

I don't understand problem 1 2 3
I will try to think
