What is the equation in vertex form of a parabola with vertex (-2, -2) that opens downward and is stretched by a factor of 5? A) f(x) = −5(x + 2)^2 + 2
B) f(x) = −5(x − 2)^2 + 2
C) f(x) = 5(x + 2)^2 − 2
D) f(x) = −5(x + 2)^2 − 2

C

Step-by-step explanation:

D).  -5(x + 2)^2 - 2.

Step-by-step explanation:

Parabola which Opens down and vertex (-2, -2) is :

f(x) = a(x + 2)^2 - 2 where a is negative

Stretch by factor 5 gives:

-5(x + 2)^2 - 2.

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
