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.

Rashid [163]

Answer:

127

Step-by-step explanation:

3 x 7 + 5 - 2 -  3 + y

y = 106

3x7 = 21

21 + 5 = 26

26 - 2 = 24

24 - 3 = 21

21 + 106 = 127
