1996 AHSME Problems/Problem 6

Solution

Plugging in $x=0$ into the function will give $0^1\cdot 2^3$ . Since $0^1 = 0$ , this gives $0$ .

Plugging in $x=-1$ into the function will give $-1^0 \cdot 1^2$ . Since $-1^0 = 1$ and $1^2 = 1$ , this gives $1$ .

Plugging in $x=-2$ will give a $0^1$ factor as the second term, giving an answer of $0$ .

Plugging in $x=-3$ will give $(-3)^{-2}\cdot -1^0$ . The last term is $1$ , while the first term is $\frac{1}{(-3)^2} = \frac{1}{9}$

Adding up all four values, the answer is $1 + \frac{1}{9} = \frac{10}{9}$ , and the right answer is $\boxed{E}$ .
