Answer 1

f(x) = x^2 , x < 2

f(x) = 5, 2\ x < 4

Explanation:

Answer 2

`f(x) = x^2 , x < 2`

`f(x) = 5, 2\leq x < 4`

Explanation:

We have a parabola and a small line shown in the graph.

The parabola goes upto x = 2 but does not reach that very value. So x = 2 starts on the line above where x = 2 and ends just before x = 4.

Therefore, this function can be modeled by:

`f(x) = x^2 , x < 2`

`f(x) = 5, 2\leq x < 4`
