Jul 14, 2017 · (-1,3) As 2 < 2x+4 <10 we have 2 < 2x+4 or 2-4 < 2x i.e. -1 < x Further, as 2x+4 < 10, we have 2x < 6 or x < 3 Hence we have -1 < x < 3, which in interval notation can be written as (-1,3) Note: Had it been -1 <= x < 3, we would have written [-1,3) i.e. for inequality with equality we use square brackets and for pure inequality we use small brackets.

Jun 30, 2016 · Range: [5, oo) FYI (general knowledge) We are talking about the y-values, so we are dealing with the range. Remember: [ or ](brackets) - include all numbers including the one inside the bracket(s) ( or )(parentheses) - include all numbers but the one noted inside the parentheses For example: [ x , y) Here, the variable x is included as a solution, but the variable y is not. FOR YOUR QUESTION ...

May 2, 2017 · x<2" "OR" "x>1hArr(-oo,oo) x<2 means x can take any value less than two and interval notation, this means (-oo,2), meaning that all numbers between -oo and 1 are included and as -oo and 2 are not included we have use small brackets. This forms one set of numbers, say P. x>1 means x can take any value greater than one and interval notation tis means (1,oo) , meaning that all numbers between 1 ...

Jan 17, 2018 · 1 < x < 2 When writing intervals as inequalities we need to remember that parentheses, like, (a,b) are equivalent to strict inequalities, so (a,b) rarr a < x < b. Brackets, like [a,b] are equivalent to inclusive inequalities, so [a,b] rarr a <= x <= b. For this problem (1,2) rarr 1 < x < 2. On a number line put 1 and 2. Put open circles at 1 and at 2. Shade the region of between the circles ...

The inequality is Quadratic in form. Step 1: We require zero on one side. x^6 + x^3 - 6 ge 0 Step 2: Since the left side consists of a constant term, a middle term, and a term whose exponent is exactly double that on the middle term, this equation is quadratic "in form." We either factor it like a quadratic, or we use the Quadratic Formula. In this case we are able to factor. Just as y^2 + y ...

May 26, 2015 · Whenever a problem asks for concave up or down intervals, we have to use the second derivative test.Concavity involves the curvature of a graph; at a given interval, taking the first derivative gives us a increasing or decreasing function linearly, while the second derivative allows us to see how a function curves up or down exponentially (like the parabola #y=x^2#, where it curves up always).

Apr 17, 2017 · How do you solve and write the following in interval notation: #5<x<13#? Algebra Linear Inequalities and Absolute Value Multi-Step Inequalities

Jul 15, 2018 · Remember, the end goal is to isolate #u#.To go about doing this, we can divide all intervals by #20#.We get #3 < u < 6#

May 12, 2017 · See a solution explanation below: Because "a is negative it is never positive and it is never equal to 0. We can write the inequality for this statement as: x < 0 In interval notation this is written as: (-oo, 0)
