What do I do next??? Help

Let g(x) = x2 _ 5 X First find the slope m of the line joining (1, g(1) ) and (2, g(2)). Then use the Newton-Raphson method to estimate the values of c for which g'(c) = m. Check that your calculator is set for at least 10 digit display. Continue the process until successive iterations obtained by the calculator are identical. m = 5.5 How many values of c in (1, 2) exist? O 2 0 3 Enter values of c below in order from least to greatest. Enter DNE in any empty answer blanks. C = C = C = symbolic formatting help
