the following graph is y= 3^sqroot x -3

true or falsee?

Answer 1

The first one could not be true because the graph contains negative y values and 3sqrt(x) cannot be negative.

Answer 2

The second one is false for the same reason.

Answer 3

What is the equation of the line which includes points (1, 1) and (1, 5)?

Answer 4

Can you find the slope?

Answer 5

These are my choices:


x = 1

y = 1

y = x + 1

y = -x - 1

Answer 6

What is the slope?

Answer 7

slope = (5-1)/(1-1)
slope = 4/0
Division by 0 is undefined so the line is vertical and its equation is x = 1

Answer 8

I have one last one:
What is the solution of -4x + 1 ≥ 7?

Answer 9

x is less than or equal to -3/2
