Triangles are similar ,

Thus :

$\frac{9}{3} = \frac{6}{x} \\$

$3 = \frac{6}{x} \\$

$\frac{6}{x} = 3 \\$

Inverse both sides

$\frac{x}{6} = \frac{1}{3} \\$

Multiply sides by 6

$6 \times \frac{x}{6} = 6 \times \frac{1}{3} \\$

$x = 2 \times 3 \times \frac{1}{3} \\$

$x = 2$

Which function is increasing?? :)

exis [7]

Answer:

$\large\boxed{B.\ f(x)=4^x}$

Step-by-step explanation:

Exponential function $f(x)=(a)^x$ is

increasing if $a > 1\to a\in(1,\ \infty)$

decreasing if $0 < a < 1\to a\in(0,\ 1)$

$A.\ f(x)=\left(\dfrac{1}{4}\right)^x\to a=\dfrac{1}{4}\in(0,\ 1)\to\text{decreasing}\\\\B.\ f(x)=4^x\to a=4\in(1,\ \infty)\to\text{increasing}\\\\C.\ f(x)=(0.4)^x\to a=0.4\in(0,\ 1)\to\text{decreasing}\\\\D.\ f(x)=\left(\dfrac{1}{2}\right)^x\to a=\dfrac{1}{2}\in(0,\ 1)\to\text{decreasing}$
