Which function represents a reflection of f(x) = 3/8 (4)x across the y-axis?

almond37 [142]

Answer:

D is correct option. $g(x)=\frac{3}{8}\cdot (4)^{-x}$

Step-by-step explanation:

We are given a function $f(x)=\frac{3}{8}\cdot (4)^x$

We need to find new function reflection of f(x) across the y-axis.

When function reflection across y-axis $x\rightarrow -x$

$\text{Reflection across y-axis}f(x)\rightarrow f(-x)$

Therefore, $f(-x)=\frac{3}{8}\cdot (4)^{-x}$

New function, $g(x)=f(-x)$

$g(x)=\frac{3}{8}\cdot (4)^{-x}$

Thus, D is correct option.
