please help me understand this problem, lads. thanks

Find where f(x) is equal to x by replacing f(x) with x, then solve for x

>>8581423
Just let x = -2x+2 and call it a day.

Is this a joke?

>>8581423
This problem is so easy it hurts not to just solve it.

A way to understand it is to find the value of x so that f(x) points to that original value.

A geometric approach would be to find the point at were the line y=x and y=-0.5x + 1 intersect.

Such a point must exist because those two lines are not parallel, given that they have a different slope. So find it.

Thank you kind anon.

I miss this shit
x=2/3

2/3
