Graphing Absolute Value Functions & Inequalities
f (x) = |3x-4|

absolute value makes everything positive instead of negative so since you didn't even really ask a question I'm just going to solve the problem without a point

f(x)=3x+4

f(x) = 3x - 4

f'(x) = x

x = 0

et

3x - 4 = 0

3x = 4

x = 4/3

3 * 0 - 4 = 0 - 4 = - 4

3 * 4/3 - 4 = 0

f(x) = I3x - 4I = I-4 ; 0I

1/800 is the right answer

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
