Evaluating a Step Function Using the Function Rule!
HELP!

ANSWER
[tex]g(2) = 3[/tex]
[tex]g( - 2) = - 4[/tex]
[tex]g(5) = 5[/tex]
EXPLANATION
The given step function have constant y-values on certain interval.
To find g(2), we plug x=2 into
g(x) =3, because 2 belongs to the interval
2≤x<4
This implies that
[tex]g(2) = 3[/tex]
To find g(-2), we substitute x=-2 into g(x)=-4, because x=-4 belongs to
-3≤x<-1
This implies that,
[tex]g( - 2) = - 4[/tex]
Similarly,
[tex]g(5) = 5[/tex]
because x=5 belongs to the interval,x≥4
Answer:
g(2)=3,
g(-2)=-4,
g(5)=5
Step-by-step explanation:
g(2) means find the value of function g(x) when x=2
from given restriction we see that x=2 lies withing [tex]2 \leq x <4[/tex]
corresponding function value is 3
Hence g(2)=3
-------
g(-2) means find the value of function g(x) when x=-2
from given restriction we see that x=-2 lies withing [tex]-3 \leq x <-1[/tex]
corresponding function value is -4
Hence g(-2)=-4
-------
g(5) means find the value of function g(x) when x=5
from given restriction we see that x=5 lies withing [tex]x \geq 4[/tex]
corresponding function value is 5
Hence g(5)=5
