Short Answer

Expert verified

The value of the function is

$\begin{array}{l} (a) 187 \\ (b) 40 \\ (c) 2 \end{array}$

Step by step solution

Step 1. Given information

$\begin{array}{l} Thegivenexpressionsis \\ f (x) = 8 x^{2} 鈭� 3 x + 2 \\ Wehavetofindthevalueofthefunction \\ (a) f (5) i.eat x = 5 \\ (b) f (- 2) i.eat x = 鈭� 2 \\ (c) f (0) i.eat x = 0 \end{array}$

Step 2. Solving for part (a)

$\begin{array}{l} Substitute x = 5 inthe f (x) \\ 鈬� f (5) = 8 {(5)}^{2} 鈭� 3 (5) + 2 \\ = 8 (25) 鈭� 15 + 2 \\ = 200 鈭� 15 + 2 \\ = 187 \end{array}$

Step 3. Solving for part (b)

$\begin{array}{l} Substitute x = 鈭� 2 inthe f (x) \\ 鈬� f (鈭� 2) = 8 {(鈭� 2)}^{2} 鈭� 3 (鈭� 2) + 2 \\ = 8 (4) + 6 + 2 \\ = 32 + 6 + 2 \\ = 40 \end{array}$

Step 4. Solving for part (c)

$\begin{array}{l} Substitute x = 0 inthe f (x) \\ 鈬� f (0) = 8 {(0)}^{2} 鈭� 3 (0) + 2 \\ = 8 (0) 鈭� 0 + 2 \\ = 0 鈭� 0 + 2 \\ = 2 \end{array}$
