The idea of a linear combination is a very general idea and appears throughout mathematics. In addition to taking a linear combination of two variables, we can take linear combinations of two functions. If we take a linear combination of two functions, we will get a new function. Let's look at an example. Let f(x)=x2β3x and g(x)=2x+2 . Then one example of a linear combination of f(x) and g(x) is 2f(x)+3g(x) We can even go a little bit farther and simplify the expression. If we do, we get 2f(x)+3g(x)=2(x2β3x)+3(2x+2)=2x2β6x +6x+6=2x2+6 Thus, we can say that 2x2+6 can be written as a linear combination of f(x) and g(x) . Determine whether each of the following functions can be written as a linear combination of f(x) and g(x) . If a function can be written as a linear combination, give the coefficients of f(x) and g(x) . If not, write NA in both coefficient boxes.

Type the correct answer in the box. use numerals instead of words. if necessary, use / for the fraction bar. a city water tank holds 20 gallons of water. a technician empties 25% of the tank. how many more gallons of water must be removed from thetank so that it has 5 of the water that it started with: the technician must removemore gallons of water for the tank to have 5 of the water that it started with.
