Find [tex]f(-3)[/tex] for the piecewise function.

[tex]\[
f(x) = \begin{cases}
2x + 2 & \text{if } x \leq 0 \\
-\frac{4}{3}x + 4 & \text{if } x \ \textgreater \ 0
\end{cases}
\][/tex]

[tex]f(-3) = \, ?[/tex]


Sagot :

To find [tex]\( f(-3) \)[/tex] for the given piecewise function, we need to determine which part of the function to use based on the value of [tex]\( x \)[/tex].

The piecewise function is defined as:

[tex]\[ f(x) = \begin{cases} 2x + 2 & \text{if } x \leq 0 \\ -\frac{4}{3}x + 4 & \text{if } x > 0 \end{cases} \][/tex]

Given [tex]\( x = -3 \)[/tex]:

1. First, we need to determine which part of the piecewise function applies to [tex]\( x = -3 \)[/tex].
2. Since [tex]\(-3 \leq 0\)[/tex], we use the first part of the function [tex]\( f(x) = 2x + 2 \)[/tex].

Now, we substitute [tex]\( x = -3 \)[/tex] into the first part:

[tex]\[ f(-3) = 2(-3) + 2 \][/tex]

Calculate the expression step by step:
[tex]\[ f(-3) = 2 \cdot (-3) + 2 \][/tex]
[tex]\[ f(-3) = -6 + 2 \][/tex]
[tex]\[ f(-3) = -4 \][/tex]

Therefore, the value of [tex]\( f(-3) \)[/tex] is:

[tex]\[ f(-3) = -4 \][/tex]
