A1 - 1st review for final

How do you find your x-intercept?

• look at the coefficient (number in front) of the x-variable

• plug in 0 for y and solve for x

• plug in 0 for x and solve for y

How do you find your y-intercept?

• look at the coefficient (number in front) of the x-variable

• plug in 0 for y and solve for x

• plug in 0 for x and solve for y

• If in slope intercept form (y=mx+b), it is your b-value.

From the equation  y = 4x - 12,
identify the y-intercept.

• 12
• 3
• -12
• 1/3

Does the graph represent a function?

• Yes, because the vertical line test shows there are no repeating input values

• No, because the vertical line test shows there are repeating input values

What is the range?

• {1, 2, 3, 4, 5, 6}

• {0, 1, 2, 3, 4, 5, 6}

• {2, 4, 8}

• {-1, 0, 1, 2, 3, 6}
