Answer 1

Answer:

A

Step-by-step explanation:

The graph shows two function:

• function f(x) is increasing exponential function of the form $f(x)=a^x$ passing through the point $(1,\frac{9}{2}).$ So, $f(1)=\frac{9}{2}\Rightarrow a^1=a=\frac{9}{2}$ and function f(x) has the expression $f(x)=(\frac{9}{2})^x;$

• function g(x) is decreasing exponential function of the form $g(x)=b^x$ passing through the point $(-1,\frac{9}{2}).$ So, $g(-1)=\frac{9}{2}\Rightarrow b^{-1}=\frac{1}{b}=\frac{9}{2},$ so $b=\frac{2}{9}$ and function g(x) has the expression $g(x)=(\frac{2}{9})^x.$

Hence, option A is true.
