What is the Y intercept of x 2 2x 3?

The vertex is (−1,4) , and is the maximum point of the parabola. The x-intercepts are (1,0) and (−3,0) . The y-intercept is (0,3) .

What is the vertex of the equation y =- X 2 2x 3?

The formula for finding the x -vertex is −b2a and to find the y -vertex, you insert the value you found for x into the formula. Using your question y=−x2−2x+3 we can establish the values of a,b, and c . c=3 .

Which is the graph of the function f/x )= x 2 2x 3?

The graph is the parabola with vertex (-1,2).

What is the range of the function f/x − x 3 2 7?

all real numbers less than or equal to 7 all real numbers greater than or equal to 7 all real numbers less than or equal to −3 all real numbers greater than or equal to −3.

What is the domain of f/x )= x2 2x 3?

The domain of the expression is all real numbers except where the expression is undefined.

What is the range of x 2 2x 3?

The range is (-∞,(-D/4a)], if ‘a’ is a negative number. Here D signifies the discriminant of the expression (D=(b^2)-4ac). Since the given expression is (x^2)-2x-3, the values of the coefficients are, a=1, b=-2, c=-3.

How do you find the range of x 2 x 3?

Hence, the range is [13/4. ∞). Step by step solution by experts to help you in doubt clearance & scoring excellent marks in exams.

What is the domain and range of y 2x 3?

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. The range is the set of all valid y values.

How do you find the range in forex?

Overall, the steps for algebraically finding the range of a function are:

1. Write down y=f(x) and then solve the equation for x, giving something of the form x=g(y).
2. Find the domain of g(y), and this will be the range of f(x).
3. If you can’t seem to solve for x, then try graphing the function to find the range.
