\bf \stackrel{distance}{d}=\stackrel{rate}{r}\cdot \stackrel{time}{t}\quad 
\begin{cases}
d=700\\
t=5
\end{cases}\implies 700=5r\implies \cfrac{700}{5}=r

The function f(x) = –x2 − 2x + 15 is shown on the graph. What are the domain and range of the function? The domain is all real n
dedylja [7]

Answer:

The domain is all real numbers. The range is {y|y ≤ 16}

Step-by-step explanation:

we have

f(x)=-x^{2}-2x+15

This is a the equation of a vertical parabola open downward

The vertex is a maximum

The vertex is the point (-1,16)

see the attached figure

therefore

The domain of the function is all real numbers ----> interval (-∞,∞)

Te range of the function is

y\leq 16

All real numbers less than or equal to 16 ----> interval  (-∞,16]
