Answer:
C
Step-by-step explanation:
A piece wise function involves two or more functions over specific intervals. The equations of the two lines are the following y=x+1 and y=-x+2. The line y=-x+2 continues to the right and has an open circle at the end. So this point is not included. This means the interval is a greater than sign but not equal to. This means C is the answer.
Answer:
(x/2)-16=f( x)
Step-by-step explanation:
f( x)=2x+32
y=2x+32
inve.rse (switc.h x an.d y)
x=2y+32
subtr.act 32 on eac.h sid.e
x-32=2y
divid.e ea.ch s.ide b.y 2
(x-32)/2=(2y)/2
(x/2)-16=y
rev.ise y a.s f( x)
(x/2)-16=f( x)

Answer: y = -2x + 4
Step-by-step explanation: In slope-intercept form or y = mx + b form,
the y is isolated or by itself on the left side of the equation.
So start by subtracting 4x from both sides.
That gives us -2y = 4x - 8.
Notice I put the x term first because in y = mx + b form,
the x term comes first on the left side of the equation.
From here, we divide both sides by -2 to get y = -2x + 4.
