Question

What is the domain and range of the quadratic equation y = –x2 – 14x – 52?

a. Domain: All Real Numbers
Range: y –3

b. Domain: All Real Numbers
Range: y –7

c. Domain: All Real Numbers
Range: y –3

d. Domain: All Real Numbers
Range: y –7

Answer 1

well, there seems to be no dispute on domain; so what does range mean?

Answer 2

equal then or greater to

Answer 3

close; range is all possible outcomes; can be greter than ot less than a specific boundary; or the set of all reals as well

Answer 4

in this case; id see if -3 or -7 produces a "bigger" y value and pick that bigger one

Answer 5

then youll have to determine which symbol is where since youre copy paste of the question omits those parts

Answer 6

The vertex would be at \[(\frac{-b}{2a},f(\frac{-b}{2a}))=(-7,-3)\]. The graph of this function is opening down, so -3 is a maximum. Range is:
\[(-\infty, -3]\]
