the graphs of functions f and g are shown below.
a) find all values of x for which f(x)=g(x).
b) find all values of x for which f(x) c) find all values of x for which f(x)> g(x).

a) x=0, x=-10, x=11

Step-by-step explanation:

Just find the x- coordinates for when f(x) intersects g(x).

the correct answer is the second option

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
