Q. Which of the following equations matches standard form of a quadratic?

answer choices

ax + by = c

y = a(x - h)² + k

y = ax² + bx + c

y = mx + b

Q. Convert the equation y= x²-2x-5 into vertex form.

answer choices

y= (x-1)²-6

y= -(x-1)²-6

y= (x+1)²-6

y= -(x+6)²-1

Q. Which of the following shows
f(x) = x² + 12x - 2
written in vertex form?

answer choices

f(x) = (x + 6)² + 142

f(x) = (x + 6)² - 34

f(x) = (x + 6)² - 38

f(x) = (x + 6)² + 34

Q. Convert the equation y= x²+4x into vertex form.

answer choices

y= (x+4)²-4

y= (x-2)²+4

y= (x+2)²-4

y= (x+2)²

Q. Which of the following equations is in vertex form?

answer choices

f(x) = x² + 6x - 2

f(x) = (x - 1)² + 2

Q. Which of the following shows
f(x) = x² - 8x + 1
written in vertex form?

answer choices

f(x) = (x - 4)² - 15

f(x) = (x - 4)² + 17

f(x) = (x - 4)² - 17

f(x) = (x - 4)² + 65

Q. Convert the equation
x²-12x+40
into vertex form

answer choices

(x+6)²-4

(x+6)²+4

(x-6)²-4

(x-6)²+4

Q. Which function is equivalent to
y = x² - 6x + 10?

answer choices

y = (x + 3)² - 1

y = (x - 3)² + 1

y = (x + 6)² - 10

y = (x - 6)² + 10

Convert the equation y= x²+ 4x + 11 into vertex form.

answer choices

y = (x + 2)² - 4

y = (x + 2)² + 7

y = (x + 2)²

y = (x - 2)² - 7
