Answer:

$f(x)=6(x-2)^2-4$

Step-by-step explanation:

The equation in vertex form is

$f(x)=a(x-2)^2 - 4$

Substituting in the coordinates (1,2) to find a,

$2=a(1-2)^2 - 4 \\ \\ 2=a-4 \\ \\ a=6 \\ \\ \therefore f(x)=6(x-2)^2-4$

2x2 − 1 = 3x + 4 Which equation correctly applies the quadratic formula?

NNADVOKAT [17]

Standard form: ax^2 + bx + c = y

Steps to simplify:

2x^2 - 1 = 3x + 4

~Subtract (3x + 4) to both sides

2x^2 - 1 - 3x + 4 = 3x + 4 - 3x + 4

~Simplify

2x^2 - 3x - 5 = 0

(a = 2, b = -3, c = -5)

Now that we know what these values are, we can use the quadratic formula to solve.

$x=\frac{-b-+\sqrt{b^2-4ac} }{2a} \\x = \frac{-(-3)-+\sqrt{-3^2-4(2)(-5)} }{2(2)}\\x= \frac{-3-+\sqrt{49} }{4} \\x=\frac{3-+7}{4} \\x = \frac{10}{4}~or~\frac{-4}{4} \\x=\frac{5}{2}~or~-1$

Answer: x = 5/2 or x = -1

Best of Luck!

Hi! I'm making some lemon macarons. 2-3 teaspoons of lemon juice is how much lemon extract? The proportions are 1 tablespoon is

Aliun [14]

Answer:

1/3 to 1/2 teaspoons of lemon extract

Step-by-step explanation:

The proportions you say are ...

1 tsp lemon extract : 2 tbsp lemon juice

extract : juice = 1 tsp : 6 tsp = 1 : 6

If you have 2-3 teaspoons of lemon juice, you have the equivalent of 2/6 to 3/6 = 1/3 to 1/2 teaspoons of lemon extract.
