Test your function in a program. 4) PE 05a 04 (Function f(x)) Write a function for f(x) and test it in a program. Evaluate the function for several values. The function should receive and return data type double. f(x) = 2x2 - 7x +4 x2+1 5) PE 05a 05 (Hypotenuse) Write a function that calculates the hypotenuse of a triangle. Test your function in a program that reads the coefficients from the keyboard with scanf as data type double using the conversion specifier X1f. Create your function using the sqrt(x) and pow(x,n) functions from the header. c = hyp(a,b) = a + b
