The function f(x) = -6x. the graph of g(x) is f(x)vertically stretched by a factor of 7 and reflected in the x-axis. what is the function rule for g(x)?

a. g(x) = -6/7x

b. g(x) = 42x

c. g(x) = -42x

d. g(x) = 6/7x

option: B( g(x)=42 x)

Step-by-step explanation:

We are given a function f(x)= -6 x

Now the graph of g(x) is:  " f(x) vertically stretched by a factor of 7 and reflected in the x-axis" .

( we know that for any function f(x) the graph g(x) which is a vertical stretch by a factor 'a' is given by:

h(x)=a f(x)

now as the function is then reflected in the x-axis this means that the resultant function is given by:

g(x)= -h(x)  )

So here we are given a vertical stretch by a factor  '7'

⇒ h(x)=7 f(x)=7×(-6)x= -42 x

also now this function is reflected in the x-axis

Now the resultant function g(x) is given by:

g(x)= -h(x)

⇒ g(x)=42 x

Hence, option B is correct.

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.
