The graph of the function f (x) = x 2 − 2 x + 3 is a parabola that opens upwards, with a vertex at (1, 2) and a y-intercept at (0, 3).There are no real x-intercepts since the function does not cross the x-axis. The function's values may create imaginary x-intercepts, indicating that it is always above the x-axis for real values of x.

Graph your problem using the following steps: Type in your equation like y=2x+1 (If you have a second equation use a semicolon like y=2x+1 ; y=x+3)
f(x) = -2x + 4. where f{x) is playing the same role as y in Equation (2) on page 285, then f(1) represents the value of the expression -2x + 4 when x is replaced by 1. f(l) = -2(1) + 4 = 2. Similarly, f(0) = -2(0) + 4 = 4. and. f(2) = -2(2) + 4 = 0. The symbol f(x) is commonly referred to as function notation. Example 3 . If f(x) = -3x + 2 ...

Two numbers r and s sum up to \frac{1}{2} exactly when the average of the two numbers is \frac{1}{2}*\frac{1}{2} = \frac{1}{4}. You can also see that the midpoint of r and s corresponds to the axis of symmetry of the parabola represented by the quadratic equation y=x^2+Bx+C.

Now that we know that m=2, we can start to build the equation of this line in y=mx+b form as follows: y = 2x + b. For the second step, we have to select one of the two (x,y) coordinates that was given to us, plug it into the slope-intercept form equation, and solve for b as follows: Let’s choose the point (2,5), where x=2 and y=5. y = 2x + b
