For the function y = ((2x ^ 2 - 5x + 4) ^ 3)/(x ^ 2), calculate the value of y for the follow ing values of x-2,-1.0, 1.2.3, 4, 5 using element-by-element operations.

y = ((2x ^ 2 - 5x + 4) ^ 3)/(x ^ 2)

What does 1.2.3 mean ?

Hint:

x = [-2, -1.0, 1, 2, 3, 4, 5]

For y = ((2x ^ 2 - 5x + 4) ^ 3)/(x ^ 2) use "dot slash" and "dot caret" instead of slash and caret. and 2x needs a * between the 2 and the x.

I think the OP meant

x = [-2, -1, 0, 1, 2, 3, 4, 5]
