Let y = f(x)
To find the x-intercepts, let y = 0 and solve for x.
To evaluate the function, select different value for x, plug them into your function and do the math. You can use any number. I will give you 4 to play with. Let x = -2, -1, 0, 1.
To graph the function, go to mathway.com and in the graph category, write the following: Graph y = -x^2 + 2x - 2.
Is this clear?
