You can solve this by algebraically as well as graphically. When I tried both ways I got:
solution is x= -2<span />
assuming the rest of your math is correct, the cone would have an area of roughly 212 sq in and the bowl roughly 157 sq inches. Therefore the one with less area is cheaper to make
Answer:
In the step by step
Step-by-step explanation:
Graph 1 : k(x)=(1/4)^x
Graph 2: f(x)=-(1/4)^x
Graph 3: g(x)=4^x
Graph 4: h(x)=-4^x
