Answer:

Step-by-step explanation:

$f(x) = x^2 + x - 1\\g(x) = x +3\\\\\\(f\:o\:g)(x) = f(g(x))$

we input the function g(x) into every x in f(x)

$f(g(x)) = (x+3)^2 + (x + 3) - 1\\f(g(x)) = x^2 + 6x + 9 + x + 3 - 1\\f(g(x)) = x^2 + 7x + 11$

Answer:

I am pretty sure $750

Step-by-step explanation:

Since there are 10 slices of cake, you would have to divded the cost ($2,500) by 10 to find out the cost per slice (you would get $250). Since we are finding the cost of 3 slices, you would mulitply 250 by 3, then you get your answer

Which function is equivalent to F(x)=-4(x+7)^2-6?

Gemiola [76]

$\huge\mathfrak\orange{answer}$

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

$f(x) = \red{-4(x+7)^2 - 6}$

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

$f(x) = -4x² - 64x - 196 - 6$

$\underline{f(x) = -4x² - 64x - 202}$

(good luck :) and mark me brainliest if you're satisfied with my answer)
