IF the function g is defined by g(x)=3x+5, what is the value of g(-5)?

Options

A. -20
B. -10
C. 20
D. 60

Answer

To find the value of \( g(-5) \) for the function \( g(x) = 3x + 5 \), we can follow these steps:

### Step 1: Identify the function
The function is given as:
\[ g(x) = 3x + 5 \]

### Step 2: Substitute \(-5\) into the function
We need to find \( g(-5) \). This means we will replace \( x \) in the function with \(-5\):
\[ g(-5) = 3(-5) + 5 \]

### Step 3: Calculate \( 3(-5) \)
Now, we calculate \( 3 \times -5 \):
\[ 3(-5) = -15 \]

### Step 4: Add \( 5 \) to \(-15\)
Next, we add \( 5 \) to \(-15\):
\[ -15 + 5 = -10 \]

### Step 5: State the final answer
Thus, the value of \( g(-5) \) is:
\[ g(-5) = -10 \]

### Final Answer
The value of \( g(-5) \) is \(-10\).
