If $$ f(x)=2 x^{2}-3 x-1 $$, then $$ f(-1)= $$ a.) 0 b.) 4 c.) -2 d.) -6

Question

UpStudy AI · Accepted Answer

To find $$ f(-1) $$ for the function $$ f(x) = 2x^2 - 3x - 1 $$, substitute $$ x = -1 $$ into the equation:

$$
f(-1) = 2(-1)^2 - 3(-1) - 1
$$

Calculate each term step by step:

1. **Square $$ -1 $$:**
   $$
   (-1)^2 = 1
   $$
   
2. **Multiply by 2:**
   $$
   2 \times 1 = 2
   $$
   
3. **Multiply $$ -3 $$ by $$ -1 $$:**
   $$
   -3 \times (-1) = 3
   $$
   
4. **Subtract 1:**
   $$
   2 + 3 - 1 = 4
   $$

Therefore, $$ f(-1) = 4 $$.
