Question

Let f (x )equals left brace Start 2 By 1 Matrix 1st Row 1st Column x if x greater than or equals 2 2nd Row 1st Column 2 if x less than 2 EndMatrixf(x)= x if x≥2 2 if x<2 . a. Find ​f(11​), ​f(22​), and ​f(99​)

Answer 1

Explanation:

Given that a function f is piecewise function as

`f(x) = x, x\geq 2\\f(x) = 2, x<2`

a)

f(11) here 11 >2

So f(11) = 11

Similarly since 22 is greater than 2

f(22) = 22

and also since 99>22

f(99) = 99

If only x value is less than 2, we get the constant funciton 2.
