svetlana [45]
Hmm, so

A(t)=740t+a₀
where a₀ is initial height or the height she started at

we want to find her initial height

after 1.5 hours, she was 710 meters above sea levl
alright
A(1.5)=740(1.5)+a₀=710
740(1.5)+a₀=710
1110+a₀=710
minus 1110 both sides
a₀=-400


so she stared at -400 meters below sea level

and the equation would be (or function)
A(t)=740t-400

Write the following as inequalities<br> Domain=<br> Range=
alina1380 [7]

Answer:

  • domain: -∞ < x < ∞
  • range: -2 ≤ y < ∞

Step-by-step explanation:

First of all, it is useful to understand what the graph is telling you. The curve tells you for input values between about -6.5 and -3.5, the output values are between -2 and about 7.5.

The arrow on the left end of the curve mean that as x goes more negative than -6.5, the y-value goes more positive than 7.5. The graph tends toward (-∞, ∞).

The arrow on the right end of the curve mean that as x goes more positive than -3.5, the y-value goes more positive than 7.5. The graph tends toward (∞, ∞).

__

The question asks about the domain and range of the function.

The domain is the <em>horizontal</em> extent of the graph, a description of all possible input values for which the function is defined. Here, that is all possible values of x: the domain is -∞ < x < ∞.

The range is the <em>vertical</em> extent of the graph, a description of all possible output values from the function. Here, the function does not produce any outputs lower than -2, but it can give any value from -2 on upward: the range is -2 ≤ y < ∞.
