Given the definitions of f(x) and g(x) below, find the value of (gºf)(9). f(x) = -x+11
g(x) = 3x^2 -x + 14

42.4 6th grade students prefer hip hop

step-by-step explanation:

40 percent of 106 = 42.4

i believe that the answer is y+6=1/3(x+2)

we have been given a piecewise function which has three parts

we can graph each part one by one.

first part is x+1 which is just like equation y=x+1

restriction with first part is x< 0 so that means we can use any number for x which is less than 0 for example x=-1 and x=-2

now plug x=-1 into y=x+1 to get y

y=x+1=-1+1=0

so the point will be (-1,0)

similarly we get another point (-2,-1)

now we graph a line joining both points but keep in mind that line must be on left side of x=0 because of restriction x< 0

same way we can graph 2nd and third parts

if we have < or > then we use open circle.

if we have < = or > = then we use close circle.

so using above information, final graph can be drawn as:
