Answer:

D. f(-2)=3

Step by step explanation:

We have been given a piece wise function:

f{x}=\left\{\begin{matrix}-x^{2}; &x< -2 \\3;&-2\leq x< 0\\x+2; & x\geq 0\end{matrix}\right

We are asked to find value of f(-2).

In our piece function when we will input values of x less than -2(x) , it will give us output as -x^{2}

For values greater than or equal to 0 our function will give output as x+2.

We can see from our piece wise function that when x is greater than or equal to -2 and less than 0 our function gives a constant output, that is 3.

Therefore, f(-2)=3 and option D is the correct choice.

f(-2)=3, because f(x)=3 for -2\leq x\ \textless \ 0

A plane travels at a constant speed. It takes 6 hours to travel 3360 miles. A. What is the planes speed in miles per hour? B. At
NemiM [27]

Answer:

the plans can go 560 miles per hour and in 10 hours it can travel 5600 miles

Step-by-step explanation:

1st divide miles over hour so you have to do 3360/6 and the solution you get for that equation is how far the plane can go in miles per hour 2nd for the second question you have to multiply your unit rate by the 10 hours so since our unit rate was 560 miles per hour you would multiply 360 and 10.
