1)a A parabola is given in four equivalent forms. Which form most quickly reveals the y-intercept of the function?

a. y = 3(x+ 3)(x- 1)

b.y = 3(x +1)² - 12

c. y= 3x² + 6x -9

d. y = 3(x² + 2x - 3)

1)b A parabola is given in four equivalent forms. Which form most quickly reveals the zeros of the function?

a. y 3(x+ 3)(x- 1)

b. y = 3(x + 1)² - 12

c. y 3x² + 6x - 9

d. y 3(x² + 2x- 3)

2)a What is the y-intercept of the below relation?

y = 2x² - 8x + 13

2)b how do i complete the square to convert the above relation below to Vertex Form. What is the value of a in the new equation?

2c) Using the same above relation in Vertex form, what is the value of k in the new equation?

2d) Using the same relation as above, which ones are the coordinates of the vertex?

(-2, 13)

(-4, 13)

(-8, 13)

(2, 5)

(-2, 5)

thank you so much. please tell me with instructions if its possible so ill learn it
