Take derivitive of each

f'(x)=9
g'(x)=4
h'(x)=12x

so duh, when x>0.75 then h(x) grows at fastest rate, after that. it just keeps going up

Answer:

\text{Exponential Function: }g(x)=4^x

B is correct.  

Step-by-step explanation:

Given:  

\text{Linear Function: }f(x)=9x+14

\text{Exponential Function: }g(x)=4^x

\text{Quadratic Function: }h(x)=6x^2+1

All the functions are specific function.  

Growth rate of these function. ( If all are in same increasing )

Exponential > Quadratic > Linear  

For increasing value of x

All three functions are increasing function.  

Please see the attachment for graph for grow.

Hence, Exponential function grow fastest rate for increasing value of x is g(x)=4ˣ

(-8, -1) slope = -3/4
babunello [35]

Answer:

y=-3/4x - 7

Step-by-step explanation:

When finding the slope given a point and a slope, we do the following.

y=mx+b  (Slope-intercept Form)

m is the slope and x,y are the points

Plug in everything

-1= -3/4(-8)+b

Multiply

-1 = 6 + b

-7 = b

This gives us the final equation of y=-3/4x - 7

Answer:

let cost of washer be x

cost of dryer be $745-x

we have

cost of washer =$95+($745-x)

x=$95+$745-x

x+x=$840

2x=$840

x=$840/2=$420

the cost of washer =$420

<h2>cost of drier </h2>

=$745-x=$745-420=$325

$325 is the cost of dryer.
