Answer:

(hk)(x) = 2x³-18x

(k/f)(x) = 2

(h/g)(x) = x+3

Step-by-step explanation:

(hk)(x)

(x² - 9)(2x)

2x³ - 18x

(k/f)(x)

2x/x

2

(h/g)(x)

(x² - 9)/(x - 3)

[x² - 3²]/(x - 3)

(x + 3)(x - 3)/(x - 3)

x + 3

Which function is equivalent to f(x)=-4(x+7)^2-6
Bess [88]

Pls mark Brainliest.

Answer:

f(x) = -4x² - 64x - 202

Step-by-step explanation:

We can simplify this quadratic function given in vertex form into standard form by simplifying the exponents and adding like terms.

f(x) = -4(x+7)^2 - 6

f(x) = -4(x^2 + 14x + 49) - 6

f(x) = -4x² - 64x - 196 - 6

f(x) = -4x² - 64x - 202

You make an x= ... equation by moving 2y to the other side and /3 (in the first equation) then you fill in x into the second equation and you calculate y. If you have Y you fill it in in the first equation.
