Question 1

1.

The table shows a quadratic function. Which function can be used to best represent the table?

y = x^{2} - 9

y = x^{2} - 3x + 18

y = x^{2} + 3x - 18

y = -8x^{2} -  48

Question 2

2.

The table contains some points on the graph of an exponential function.
Based on the table, which function represents the same relationship?

q(x) = (0.25)^{x}

q(x) = 256 (0.25)^{x}

q(x) = 0.0625(4)^{x}

q(x) = 0.5 (4)^{x}

Question 3

3.

What is the equation in slope-intercept form of the line that passes through the points
(-4, 2) and (12, 6)?

y=\frac{1}{4}x + 3

y = \frac{9}{2}x - \frac{1}{4}

y = \frac{1}{4}x - \frac{9}{2}

y=3x + \frac{1}{4}

Question 4

4.

The table represents some points of the graph of a linear function. Which function represents the same relationship?

 y = 4x - 3

y = 4x + 3

 y = 4x + 102

y = 4x - 102
