Mathematical Applications: Distance, Midpoint,and Piecewise FunctionsA.1. Find the distance between the points (-2,3) and (1,-1).Answer: The equation to calculate the distance between thepoints (a,b) and (c,d) isd=โˆš(๐‘Žโˆ’๐‘)2+(๐‘โˆ’๐‘‘)2So the distance between the points (-2,3) and (1,-1) isd=โˆš(โˆ’2โˆ’1)2+(3โˆ’(โˆ’1))2=โˆš32+42=52.Find the midpoint of the line segment joining the points (-2,3) and (1,-2)Answer:Themidpointofthepoints(a,b)and(c,d)is(๐‘Ž+๐‘2,๐‘+๐‘‘2), so the midpoint of (-2,3) and (1,-1) is(โˆ’2+12,3โˆ’12) = (-1/2,1)The midpoint is (-1/2,1)G. The function of f(x) is defined as:f(x) =1.a.Findf(0), f(2), f(5)0 is in the range2โ‰คx<1, so f(0)=-2*0+3=32 is in the range 1โ‰คxโ‰ค2, so f(2)= 55 is in the rangex>2, so f(5)= 5^2+2=27b.Determine the domain of f(x)The domain is (-โˆž,โˆž)-2x+3if-2โ‰คx<15if1โ‰คxโ‰ค2x^2+2ifx>2
