If f(x) = x^2 - 4x + 3, and the domain is {-2, 0, 1}, what is the range? a) {7, 3, 0} b) {-9, 3, 1} c) {-1, 3, 1} d) {15, 3, 0}

Using the concepts of domain and range, it is found that the range of the data-set is {15,3,0}, given by option D.

------------------------

The function is:

Applying for every value in the domain:

Thus, the range is {15,3,0}, given by option D.

A similar problem is given at link

Evaluate the function at the three values of the range and see what you get. The appropriate choice is ...

... D) {15, 3, 0}

Evaluation can sometimes be simpler if you rearrange the function to a form called "Horner's form."

... f(x) = (x -4)x +3

Then the evaluation looks like (for x=-2) ...

... f(-2) = (-2-4)(-2)+3 = (-6)(-2) +3 = 12 +3 = 15

This is sufficient to identify D as the answer of choice.

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.
