How do you look at a graph and tell what the quadratic function i?

To determine the quadratic function from a graph, first identify the shape of the parabola, which can open upwards or downwards. Look for key features such as the vertex, x-intercepts (roots), and y-intercept. The standard form of a quadratic function is ( f(x) = ax^2 + bx + c ), where ( a ) indicates the direction of the opening. By using the vertex and intercepts, you can derive the coefficients to write the specific equation of the quadratic function.


What are the steps for the quadratic formula?

Put the quadratic equation into standard form; identify the coefficients (a, b, c), replace them in the equation, do the calculations.


How do you identify the y-intercept of a quadratic equation?

You replace x = 0, and do the calculations.


What would identify an expression as quadratic?

An expression is quadratic is the equation is in the form ax2 + bx + c. a, b, and c are all constants. They may be different or equal.


How do I find the nth term in a quadratic sequence?

To find the nth term in a quadratic sequence, first identify the first and second differences of the sequence. The second difference should be constant for a quadratic sequence. Use this constant to determine the leading coefficient of the quadratic equation, which is half of the second difference. Next, use the first term and the first difference to derive the complete quadratic formula in the form ( an^2 + bn + c ) by solving for coefficients ( a ), ( b ), and ( c ) using known terms of the sequence.
