A function that will convert women's shoe sizes in the United States to those in Australia is $$ s(x)=\frac{2 x-3}{2} $$ (Source: OnlineConversion.com). a) Determine the women's shoe sizes in Australia that correspond to sizes \(5,7 \frac{1}{2},\) and 8 in the United States. b) Find a formula for the inverse of the function and explain what it represents. c) Use the inverse function to determine the women's shoe sizes in the United States that correspond to sizes \(3,5 \frac{1}{2},\) and 7 in Australia.
Consider quadratic functions ( \(a\) )-( h ) that follow. Without graphing them, answer the questions below. a) \(f(x)=2 x^{2}\) b) \(f(x)=-x^{2}\) c) \(f(x)=\frac{1}{4} x^{2}\) d) \(f(x)=-5 x^{2}+3\) e) \(f(x)=\frac{2}{3}(x-1)^{2}-3\) f) \(f(x)=-2(x+3)^{2}+1\) g) \(f(x)=(x-3)^{2}+1\) h) \(f(x)=-4(x+1)^{2}-3\) Consider (a) and (c). Which graph is narrower?
Solve using any method. $$5^{2 x}-3 \cdot 5^{x}+2=0$$
