Linear Regression

  1-Consider the function: f(x) = 2x+3 a) Find the slope b) Find the y-intercept c) Use the slope and the y-intercept to graph this function. d) Find the average rate of change 2-Consider this function” H(x)= -3x+4 a) Find the domain b) Find the y-intercept c) Find the average rate of change d) State if the graph is increasing or decreasing. 3-Consider f(x) = 4x-1 and g(x) = -2x+5 a) Solve f(x) =g(x) b) Solve f(x)>0
