Given:
descends at a rate of 320 feet per minute for 3 minutes.
320 feet per minute * 3 minutes = 960 feet
Total change in altitude is 960 feet. Since it is descending, I believe it would be a negative 960 feet.
Answer:
All real numbers
(-∞, ∞)
Step-by-step explanation:
Domain is the set of x-values that can be inputted into function f(x).
We see here that our function is a parabola. We also see that we can plug in any number <em>x </em>and we would get an output <em>y</em>. Therefore, our domain is all real numbers:
(-∞, ∞)
X^2 + 3x - 4 = 6
x^2 + 3x - 10 = 0 (Now reverse FOIL)
(x + 5)(x - 2)(Now x will equal the opposites of your numbers)
x = -5
x = 2
Hope this helped!
