I need help please I don’t understand this

f(1)= 1

Step-by-step explanation:

So assuming you're doing basic functions, f(x) just means "function of x".

This means that x is your input. So once you plug in the x value, you will see that when the x value of your function is 1, the y value is 1 as well.

This will be marked brainliest if correct ok?

2 in a half from f 2 and a half (2 1/2) units down from line. I'm not sure though but you just have to listen to your teacher help yall learn and you'll know! PLSSS MARK ME BRAINLIEST OR COMMENT ME OR STAR ME OR THANK ME OR SOMETHING PLSSS

b i think

step-by-step explanation:

not really sure

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
