What is the value of h(a) when a = 2 in the

Ivahew [28]

<h3>Answer: 3</h3>

=========================================================

Explanation:

This is the given piecewise function

$h(a) = \begin{cases}3a+2 \text{ when } a > 3\\4a+5 \text{ when } a = 3\\3 \text{ when } a < 3\\\end{cases}$

We can rewrite things like this

$\text{when } a > 3, \ \ h(a) = 3a+2\\\text{when } a = 3, \ \ h(a) = 4a+5\\\text{when }a < 3, \ \ h(a) = 3\\$

I personally prefer this format better because it mentions the inputs first, and that leads to which function definition we go for.

The input a = 2 fits the description of $a < 3$ since $2 < 3$ is a true statement. Therefore we go for the third line and can see that $h(a) = 3$ becomes $h(2) = 3$

-----------

As another example, if we had the input a = 7, then we'd go for the first line (since 7 > 3) and get

h(a) = 3a+2

h(7) = 3(7)+2

h(7) = 23
