7. The following values were measured at 1- metre intervals. Plot and apply simple 3-point and 5-point filters. What are the maximum and minimum values of the unfiltered and two filtered data sets? What are the most obvious wavelengths in each case? –3, 2, 1, 4, 0, 4, –1, 3, 0, 1, –4, 0, –4, –1, –4, 1, 0, 2, 4.

Maxima and minima are+ 4,-4; 2.67,-3; 2.2, -2.6, respectively.

The first and most noticeable wavelengths are 2 m and around 15 m however the 3-and 5-point filters gradually decrease the amplitude of the 2-m wave-length.

the thermometer is precise but not accurate

step-by-step explanation:

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.

you,
