How can you determine if a function is a quadratic function from its equation?
If the highest exponent of independent variable(say x) is 2 and the highest exponent of dependent variable(say y) is 1 and x and y are not multiplied, then the function is quadratic. For example: 3x-y+x2= 2y-5x+7 represents a quadratic function but y= xy+x2+5 doesn't represent a quadratic function.
Write a quadratic function f x for the area of a rectangle with a length of x plus 5 and a width of 3x-7?
Area of rectangle: (x+5)(3x-7) = 3x2+8x-35
Is 2x2 plus 7 equals 79 linear or quadratic?
It is a quadratic equation that has 2 solutions
Solve this quadratic equation using the quadratic formula 2x2 - 10x plus 7 equals 0?
2x2-10+7 = 0 Solving the quadratic equation using the quadratic formula will give you two solutions and they are: x = (5 - the square root of 11)/2 or x = (5 + the square root of 11)/2
Find a composite number to satisfy this equation x2 -x plus 41?

What is the quadratic function of x2 plus 6x-7?
x2+6x-7 = (x+7)(x-1) when factored
Find the value or values of y in the quadratic equation y to the second power plus 4y plus 4 equals 7?
The quadratic formula provides the answer easily. y=-2-Sqrt(7) or y=-2+Sqrt(7) where Sqrt(7) is the square root of 7.
