Converting Vertex and standard forms of quadratics/Solve

Convert

f(x) = 3(x - 5)² - 1

to standard form.

• f(x) = 3x² -30x + 74

• f(x) = 3x² -10x + 24

• f(x) = 3x² -30x + 24

• f(x) = 3x² -30x + 75

Convert

f(x) = 2(x - 2)² +9

to standard form.

• f(x) = 2x² + 8x + 9

• f(x) = 2x² - 8x - 4

• f(x) = 2x² - 8x + 17

• f(x) = 2x² - 8x + 8

Convert

f(x) = -4(x - 1)² +7

to standard form.

• f(x) = -4x² + 3

• f(x) = -4x² - 8x + 17

• f(x) = -4x² +8x - 11

• f(x) = -4x² +8x + 3

Convert to vertex form.

• y=-(x-5)² + 21

• y=-(x+5)² + 21

• y=-(x+10)² + 21

• y=-(x-10)² + 21

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)
