In slope intercept form (y=mx+b) what is the "m"?

• The y-intercept
• The x-intercept
• The slope (rate of change)
• A point

Which equation represents the following graph?

• y = 3x + 2
• y = -2x + 3
• y = 2x + 3
• y = -3x + 2

Find the slope of the line that passes through the points (2, 4) and (6, 12)

• 1/2
• -1/2
• 2
• -2

Name the parent function.

• square root
• quadratic
• cubic
• exponential

DOMAIN?

• (-∞,∞)
• [0,∞)
• (-∞,0]
• [-∞,∞]

RANGE?

• (-∞,∞)
• [0,∞)
• (-∞,0]

f(x) = -√(x) - 2

• Reflect over x-axis
  Down 2
• Reflect over y-axis
  Up 2
• Reflect over x-axis
  Up 2
• Reflect over y-axis
  Down 2

What is the equation of this graph?

• f(x) = (x + 2)² - 3
• f(x) = (x - 2)² - 3
• f(x) = |x + 2| - 3
• f(x) = |x - 2| - 3

If the blue is f(x)=x^2, then the red must be

• g(x)=x²-5
• g(x)=x²+5
• g(x)=(x-5)²
• g(x)=(x+5)²

g(x)=f(x)-4
Describe the transformation to f(x) that results in g(x).

• f(x) has been translated down 4.
• f(x) has been translated up 4.
