Question

Determine wheather the equation defines y as a function of x

y = 2x^2 -3x + 4

can someone please show me step by step how to solve this problem?

Step 1

Given a equation with variables y and x as shown below. We need to check if the equation defines y as a function of x.

The equation will define y as a finction of x, if and only if there is only one y value for one x value resectively according to definition of a function.

Step 2

Given euqation of y in terms of x and it is quadratic equation. So we can say that for one value of y there can be two v...
