For the function f(x) = -2(x + 3)2 -1, identify the vertex, domain, and range. (2 poin

See below in bold.

Step-by-step explanation:

f(x) = -2(x + 3)^2 - 1

Comparing this  to the standard  f(x) = a(x - b)^2 + c where (b, c) is the vertex.

The vertex  is (-3, -1).

The domain is All real x.

The range is f(x) ≤ -1.

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
