Question

Select one:

A. g(x) = x2 − 1
B. g(x) = x2 + 1
C. g(x) = 2x2 − 1
D. g(x) = 2x2
E. g(x) = 3x2 − 2

Answer 1

C

Explanation:

We can see that the y int is -1 which eliminates B D and E.

Next we can test one of the equations by plugging in one of values from table.

From this we can see that C is correct.

Answer 2

C

Explanation:

plug the first point in (0), cancels out B, D, E bc g(x) doesnt equal to -1

now the two left are A and C, plug in 1, A doesn't work because 1^2-1=0, not 1

C works because 2(1)-1 = 2-1= 1
