Evaluate the Function f(x)=4x^2+2x-1 at x=0

$f (x) = 4 x^{2} + 2 x - 1$ at $x = 0$

Replace the variable $x$ with $0$ in the expression.

$f (0) = 4 {(0)}^{2} + 2 (0) - 1$

Simplify the result.

Simplify each term.

Raising $0$ to any positive power yields $0$ .

$f (0) = 4 \cdot 0 + 2 (0) - 1$

Multiply $4$ by $0$ .

$f (0) = 0 + 2 (0) - 1$

Multiply $2$ by $0$ .

$f (0) = 0 + 0 - 1$

Simplify by adding and subtracting.

Add $0$ and $0$ .

$f (0) = 0 - 1$

Subtract $1$ from $0$ .

$f (0) = - 1$

The final answer is $- 1$ .

$- 1$
