Write an equation of the parabola in vertex form that passes through (0, -24) and has vertex (-6,-12)

stich3 [128]

Answer:

f(x)=-2(x+6)-12

Step-by-step explanation:

so the easiest one to do would be vertex form

f(x)=a(x-h)+k

so your vertex represents (h, k)

so plug in those values

f(x)=a(x- - 6) -12

now use the other point to solve for a

-24=a(0+6)+12

-24=6a+12

-12=6a

-2=a

F(x)= x^3-4x^2+9 and let g(x)=6x^3+x^2-5x-12 what is f(x)-g(x)

Anarel [89]

$f(x) - g(x) = -5x^3-5x^2+5x +21$

Step-by-step explanation:

Given functions are:

$f(x) = x^3-4x^2+9\\g(x) = 6x^3+x^2-5x-12$

We have to find the difference of functions

So,

$f(x) - g(x) = x^3-4x^2+9 - (6x^3+x^2-5x-12)\\= x^3-4x^2+9-6x^3-x^2+5x+12$

Combining like terms

$x^3-4x^2+9-6x^3-x^2+5x+12\\=x^3-6x^3-4x^2-x^2+5x+9+12\\= -5x^3-5x^2+5x +21$

Hence,

$f(x) - g(x) = -5x^3-5x^2+5x +21$
