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

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

Simplify each expression <br> 4+8(-2n+3)

artcher [175]

Answer:

28 -16n

Step-by-step explanation:

Use the distributive property, then collect terms.

4 +8(-2n +3)

= 4 +8(-2n) +8(3)

= 4 -16n +24

= 28 -16n

_____

This could also be written

-16n +28

but then the leading sign would be negative. Sometimes leading minus signs get lost, so I prefer the first term to be positive.
