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.

i think it is 18

one of the most important purposes of surface treatment is to alter surface properties according to the requirement of specific applications. for example, hydrophobic coating has been utilized on windshield and eyeglasses. gold atom monolayer on substrate has become a popular surface bioconjugation strategy.
