Question

10- Refer to the function . f= {(6,10), (-5,8), (4,6), (2,7)}For what value of X for which f(x)=10 is {.......} ?

Answer 1

6

1) Examining the function, we can tell that f(x) and y stand for the same.

$\begin{gathered} f(x)=10 \\ y=10 \end{gathered}$

2) So, looking at the set of points. We can tell that when f(x)=10, x is equal to 6
