Question

Calculate the Correct matching value for each function below (Piecewise):

Answer 1

\[f(x)=\left[\begin{matrix}-3x ^{2}+2 & x <-1 \\ x+7 & x \ge-1\end{matrix}\right] x=-2\]

Find y

Answer 2

\[f(-2) = -3*(-2)^{2}+2\]

Answer 3

=-10
but what about the x+7?

Answer 4

since -2 < -1 you use the first equation of the piece wise equation. The second equation is only used when x>-1 or x= -1

Answer 5

OH okay that makes things make sense...:) Thanks a ton!
