Explanation The given inequality is 21 + 4 x − x 2 ≥ 0 . For solve the inequality 21 + 4 x − x 2 ≥ 0 , first solve the equation 21 + 4 x − x 2 = 0 . x 2 − 4 x − 21 = 0 x 2 − 7 x + 3 x − 21 = 0 x ( x − 7 ) + 3 ( x − 7 ) = 0 ( x + 3 ) ( x − 7 ) = 0 On further simplification, the solution of the equation becomes, x + 3 = 0 or x − 7 = 0 x = − 3 or x = 7 , These roots of the equation divide the real line into three intervals such as ( − ∞ , − 3 ) , ( − 3 , 7 ) and ( 7 , ∞ ) . From Figure 1, it is clear that − 3 and 7 locate on a number line. Now, determine the interval which satisfies the inequality 21 + 4 x − x 2 ≥ 0 . Consider the number − 4 from the interval ( − ∞ , − 3 ) . Then, the inequality 21 + 4 x − x 2 ≥ 0 becomes, 21 + 4 x − x = 21 + 4 ( − 4 ) − ( − 4 ) 2 = 21 − 16 − 16 = 21 − 32 = − 11 That is, the number − 4 does not satisfies the inequality 21 + 4 x − x 2 ≥ 0

Equations and Inequations

Equations and inequalities describe the relationship between two mathematical expressions.

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
