Describe and correct the error a student made when writing the quadratic function f(x)=2(x+3)^2-4 in standard form The student did not
A. Compute 9-4 correctly
B. Compute (x+3)^2 correctly
C. Distribute 2 to all necessary terms
The function in standard form is f(x)=

y = 2x^2 + 12x + 14

Step-by-step explanation:

Write this equation in standard form.  Start by performing the exponentiation:

y = 2(x^2 + 6x + 9) - 4

Perform the indicated multiplication:

y = 2x^2 + 12x + 18 - 4, or

y = 2x^2 + 12x + 14:  This is the quadratic function in standard form.

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%

you.
