Evaluate the Function g(a)=-2a+3 when a=-1

$g (a) = - 2 a + 3$ when $a = - 1$

Replace the variable $a$ with $- 1$ in the expression.

$g (- 1) = - 2 \cdot - 1 + 3$

Simplify the result.

Multiply $- 2$ by $- 1$ .

$g (- 1) = 2 + 3$

Add $2$ and $3$ .

$g (- 1) = 5$

The final answer is $5$ .

$5$
