Finite Math Examples

f (x) = x - 1

$f (x) = x - 1$ ,

h (x) = 2

$h (x) = 2$

Step 1

Set up the composite result function.

f (h (x))

$f (h (x))$

Step 2

Evaluate

f (2)

$f (2)$ by substituting in the value of

h

$h$ into

f

$f$ .

f (2) = (2) - 1

$f (2) = (2) - 1$

Step 3

Subtract

1

$1$ from

2

$2$ .

f (2) = 1

$f (2) = 1$
