Question

Help please!!! I need help with this math problem and I don’t understand

Answer 1

6

Explanation:

6 is greater than or equal to 5.

According to the condition if x, or 6 in this case greater than or equal to 5, then the answer is just x.

In this case x is 6.

Therefore, f(6) = 6

Answer 2

6

Explanation:

Piecewise functions have different rules for different x-values.

Piecewise Functions

Piecewise functions are defined by different functions for different domains. This means that depending on the x-value you are solving for, you need to use a different function. In the piecewise function above, there are 3 separate functions. Each of these functions applies for a different domain. For example, we should use the function 3x + 3 when solving for an x-values less than or equal to 0.

Solving for f(6)

First, we need to find which domain 6 falls into. Since 6 is greater than 5, we should use the last domain, x ≥ 5. This means that the function we need to plug 6 into is x.

• f(6) = 6

So, in this piecewise function, f(6) is 6.
