I have a problem with linear funtion is f(8)=8
f(x) = x + 10=what is x is that always 0 so this answer would 10

The equation f(x) = x + 10 can be read as "f of x equals x plus 10" and it is an expression of a linear function. The general form of a linear function is "y = mx + b" where "m" represents the slope (or rate of change) and "b" is the y-intercept (or where the line crosses the y-axis). In this case, m=1 and b=10. Therefore, when x=8, y=18. The answer to your question is 10.
