Two numbers r and s sum up to 10 exactly when the average of the two numbers is \frac{1}{2}*10 = 5. 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.How do you solve quadratic inequalities? To solve a quadratic inequality write the inequality in the standard form ax^2 + bx + c < 0 or ax^2 + bx + c > 0, find the roots of the quadratic equation. Use the roots to divide the number line into intervals. Determine the sign of the expression in that interval.Two numbers r and s sum up to -3 exactly when the average of the two numbers is \frac{1}{2}*-3 = -\frac{3}{2}. 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. Solution: Degree of numerator = 1. Degree of denominator = 2. Since the degree of the numerator is smaller than that of the denominator, the horizontal asymptote is given by: y = 0. Problem 6. Find the horizontal and vertical asymptotes of …

f (x) = x2 f ( x) = x 2. The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined. Interval Notation: (−∞,∞) ( - ∞, ∞) Set -Builder Notation: {x|x ∈ R} { x | x ∈ ℝ } The range is the set of all valid y y values.

The derivative of a function f(x) is written f'(x) and describes the rate of change of f(x). It is equal to slope of the line connecting (x,f(x)) and (x+h,f(x+h)) as h approaches 0. Evaluating f'(x) at x_0 gives the slope of the line tangent to f(x) at x_0.An exponential function is a Mathematical function in the form f (x) = a x, where “x” is a variable and “a” is a constant which is called the base of the function and it should be greater than 0. The most commonly used exponential function base is the transcendental number e, which is approximately equal to 2.71828.

We're given a table of values and told that the relationship between x and y is linear. Then we're asked to find the intercepts of the corresponding graph. The key is realizing that the x -intercept is the point where y = 0 , and the y -intercept is where x = 0 . The point ( 7, 0) is our x -intercept because when y = 0 , we're on the x -axis.Scientific Calculator. web2.0calc.com online calculator provides basic and advanced mathematical functions useful for school or college.
