Question

Peacewise Function:
f(x)=12 if x<-3
15 if -3<=x<6
20 if x>= 6

Answer 1

Can someone explain it step by step please? :)

Answer 2

hmm explain? what do you need from \(\large f(x)
\begin{cases}
12\qquad &x<3
\\ \quad \\
15\qquad &-3\le x<6
\\ \quad \\
20\qquad & x\ge 6
\end{cases}\quad ?\)

Answer 3

Evaluate the piecewise function for x = -1 and x = 3 it says

Answer 4

hmmm I missed a sign there... anyhow \(\large f(x)
\begin{cases}
12\qquad &x<-3
\\ \quad \\
15\qquad &-3\le x<6
\\ \quad \\
20\qquad & x\ge 6
\end{cases}\)

Answer 5

So am I supposed to plug something in ?

Answer 6

f(x)=15 for x=-1 to 3

Answer 7

f(-1)=15
f(3)=15

Answer 8

Thank you :)

Answer 9

you got it.

Answer 10

you take any value between 13 and 6
f(x)=15

Answer 11

correction -3

Answer 12

at x=-3,it is 15
at x=6 ,it is 20
