This function opens up. What does that tell you about the value of "a" for this function in vertex form?

• "a" is positive.

• "a" is less than one.

• "a" is greater than 1.

• "a" is negative.

What is the axis of symmetry for this function? (Remember to type your answer as an equation.)

Does the function look stretch or compressed? If it does by what factor was it compressed or stretched?

What is the location of the vertex of this parabola?

Write your answer as a coordinate: (x,y)

If given the equation
y = 3(x + 5)² - 4,
what is the vertex of the parabola?

• (5, -4)
• (-5, -4)
• (-15, -4)
• (15, -4)

Which function has a translation of 3 units to the left?

• f(x) = 3x²+1
• f(x) = (x + 3)² + 1
• f(x) = (x - 3)² + 1
• f(x) = (x + 1)²- 3

Which function has a translation of 2 units right and a vertical stretch by a factor of 5?

• f(x)= 5(x - 2)²
• f(x) = 5(x + 2)²
• f(x) = (x - 2)² - 5
• f(x) = (x + 2)² + 5

Which of the following is the correct equation for the given graph?

• f(x) = (x - 2)² - 1
