What is the degree of a quadratic function?
A quadratic function will have a degree of two.
What is quadratic inequality in one variables?
A quadratic inequality in x is in the standard form of ax^2+bx+c(>or<)d. Ex. 3x^2+5x+1>4
Is yx3cubed plus x2squared a quadratic inequality?
No. This is not an inequality, because you need something > something_else, or less than or 'not equal' or 'greater than or equal', etc. Since it has an x cubed term, it is not a quadratic.
How do you tell a linear inequality from a quadratic inequality?
In a linear inequality the variable is only present raised to the first power (which is usually not explicitly shown). In a quadratic the square of the variable is present (or implied). The square can be implied in an inequality such as x + 1/x < 6 (x not 0) This is equivalent to x2 - 6x + 1 < 0
How can the change in x affect the change in y in a inequality?
The answer depends on the nature of the inequality: whether it is linear, quadratic or has some other functional form.
