The black graph is the graph of y = f(x). Choose the equation for the
red graph.
a. y = f(2x)
b. y=f)
C. 2y = f(x)
d. = f(x)

9514 1404 393

  c. 2y = f(x)

Step-by-step explanation:

Each point on the red graph is half the distance from the x-axis as the same point on the black graph. That is, the vertical scale factor is 1/2:

  y = (1/2)f(x)

Multiplying this equation by 2 gives one that matches an answer choice:

  2y = f(x)

-4

step-by-step explanation:

(-4+8)=-(4-8)=-8+4=-4

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.
