Please help loves, thank you I appreciate it <3 Evaluate the piecewise function for x = -2 and x = 2, and x = 6 g(x)={9x−2 if x <-3 {x^2−3 if -3 ≤ x < 1 {5 if x≥1

HI!!

OpenStudy (freckles):

so for x=-2... which inequality is -2 a member of ?

OpenStudy (freckles):

x<-3? -3<=x<1? x>=1?

OpenStudy (anonymous):

the second one @freckles

OpenStudy (freckles):

-2 is in between -3 and 1 great so we will use x^2-3 to evaluate x=-2

OpenStudy (freckles):

(-2)^2-3=?

OpenStudy (anonymous):

1

OpenStudy (freckles):

yes so g(-2)=1

OpenStudy (freckles):

now to evaluate g at x=2 we need to look at the inequalities again

OpenStudy (freckles):

which inequality is 2 a member of

OpenStudy (freckles):

1st 2nd or 3rd?

OpenStudy (anonymous):

3rd

OpenStudy (freckles):

yes so it says when we have that the x value is a member of x>=1 that g(x)=5 so g(2)=5

OpenStudy (freckles):

g(6) should be pretty easy for you now

OpenStudy (freckles):

what do you think g(6) equals?
