Rewrite the function f(x)=3(x-1)^2+9 in the form f(x)=ax^2+bx+c
Otrada [13]

Answer:

f(x) = 3x² - 6x + 12

General Formulas and Concepts:

  • Order of Operations: BPEMDAS
  • Expand by FOIL (First Outside Inside Last)
  • Standard Form: f(x) = ax² + bx + c
  • Vertex Form: f(x) = a(bx + c)² + d

Step-by-step explanation:

<u>Step 1: Define function</u>

Vertex Form: f(x) = 3(x - 1)² + 9

<u>Step 2: Find Standard Form</u>

  1. Expand by FOILing:                         f(x) = 3(x² - 2x + 1) + 9
  2. Distribute 3:                                      f(x) = 3x² - 6x + 3 + 9
  3. Combine like terms (constants):     f(x) = 3x² - 6x + 12

The sum of three numbers is 84, the second number is 2 times the 3rd , the first number is 8 more than the 3rd. What are the num
hjlf

Answer:

a = 27

b = 38

c = 19

Step-by-step explanation:

a + b + c = 84

b = 2c

a = 8+c

8+c +2c+c = 84

4c + 8 = 84

4c = 76

c = 19

b = 2(19) = 38

a = 8 + 19  = 27

Is (-5,-8) a solution of y&gt;3x+6
yuradex [85]

Answer:

yes

Step-by-step explanation:

To figure out if a point works with it's equation, you should replace the x and y with the point you got

-8 > 3(-5)+6

-8 > -15 +6

-8 > -9

Since -8 is bigger than -9, point (-5,-8) is true to the equation.

and as seen in the graph I have attached, the point does infact reside in the shaded in area. If you haven't learned how to graph this type of equation, you may disregard the graph :)

If you have any questions at all, don't be afraid to ask :)
