Create the equation of a quadratic function, in standard form

f(x) = 4x² + 8x - 12

Step-by-step explanation:

f(x) = ax² + bx + c , a ≠ 0

Coordinates of vertex are ( - 1, - 16)

x-coordinate of vertex is ( - )

- = - 1 ⇒ b = 2a

y-coordinate of vertex is ( )

= - 16

a(- 3)² + 2a(- 3) + c = 0 ⇒ c = - 3a

4a(- 3a) - (2a)² = - 64a

- 12a² - 4a² = - 64a ...... (1)

(1) ÷ (- 4a)

4a = 16 ⇒ a = 4

b = 8

c = - 12

f(x) = 4x² + 8x - 12

answer: 1722

step-by-step explanation:

given: the mass of saturn=

the mass of mercury=

the number of times the mass of saturn is greater than the mass of mercury

hence, the mass of saturn is 1722 times greater than the mass of mercury.

so then what are you asking?
