Question

f(−4) =
Question 2
Function 2:

f(x)=12x−3


f(−4)=
Question 3
Function 3:

f(x)=|x|+5


f(−4)=

Answer 1

Let's solve each question step by step.

### Question 2
For the function \( f(x) = 12x - 3 \), we need to find \( f(-4) \).

\[
f(-4) = 12(-4) - 3
\]

Calculating this:

\[
f(-4) = -48 - 3 = -51
\]

So, \( f(-4) = -51 \).

---

### Question 3
For the function \( f(x) = |x| + 5 \), we will find \( f(-4) \).

\[
f(-4) = |-4| + 5
\]

Calculating this:

\[
f(-4) = 4 + 5 = 9
\]

So, \( f(-4) = 9 \).

In summary:
- For Question 2: \( f(-4) = -51 \)
- For Question 3: \( f(-4) = 9 \)
