PLEASE I NEED HELP WITH MY PYTHON PROGRAM!!!!!!!!!!!!!!
I need help when users input 3 to calculate the area of the rectangle and trapezoid. So far I have caculated both
but, I dont know how to code the 3rd option when users wants to calculate both area.
Here is my code!
def f1(x):
return 5*x**4 + 3*x**3 - 10*x + 2
def f2(x):
return x**2 - 10
def f3(x):
return 40*x + 5
def f4(x):
return x**3
def f5(x):
return 20*x**2 + 10*x - 2
print(\"1 - 5x^4 + 3x^3 - 10x +2 \")
print(\"2 - x^2 -10 \")
print(\"3 - 40x +5 \")
print(\"4 - x^3 \")
print(\"5 - 20x^2 + 10x -2 \")
print(\"6 - quit \")

Needs to calculate both rectanlge and trapezoid for each function
}
