Hey , could you solve this question by using Linear algebra methods (not calculus ) you can solve it by matrix .

also please do not use any computer software in the solving .

i will rate you

The monthly profit of a company is decreasing due to the Covid-19 pandemi (Figure-1). An estimation of the profit for the next month is required in order to decide some investments. a) use linear (Cx+D) estimation and determine the next month's profit expectation. b) use a second order function (Cx+Dx+E) to estimate the next month's profit expectation.c) Which estimation is better? Show the better one by showing the total error is lower. Profit (x1000$) X 55 40 2 3 4 5 6 Month -10 -130 X
