How do you solve and write the following in interval notation: −2(x − 1) − 12 <2(x + 1)? Algebra Linear Inequalities and Absolute Value Multi-Step Inequalities

Oct 31, 2016 · How do you write the solution of 3x − 8 ≥ − 7x + 12 in interval notation? Algebra Linear Inequalities and Absolute Value Multi-Step Inequalities

Explanation: The given function is defined for all real values of x, except x=3, which makes it undefined. Hence the domain of f (x) is all real numbers excluding x=3.

Set notation: {x | -25 < x < 30} Interval notation: (-25, 30) The set notation is pretty explanatory. We always use curly brackets, or the "{}" around everything. This pretty much says "x, when …

The domain is x in [-4,1)uu (1,+oo) in interval notation. -4<=x<1 and, 1< x <+oo in inequality notation The function is M (x)= (sqrt (x+4))/ (x-1) There are 2 conditions What's under the …

Here in f (x)=sqrtx/ (x^2+x-2) As we have sqrtx in numerator, x cannot take negative values, hence we should have x>=0 Further denominator can be factorized to (x+2) (x-1), hence x …

( -8 ) <= x <= ( -4 ) OR x >= 9 Interval Notation: [ -8, -4 ] uu [ 9, oo ) We are given the inequality ( x + 8 ) ( 2z + 8 ) ( 3x - 27 ) >= 0 We will factorize as much as possible as follows: (x + 8) * 2 (x + …

Jun 4, 2015 · f (x) = y = −4x −3 x −2 = (− 4x +8) −11 x − 2 = −4(x −2) −11 x − 2 = − 4 − 11 x −2 f (x) can take any value except −4 (to which f (x) is asymptotic as x → ± ∞). So the range is R \ …

Solve the polynomial inequality and express in interval notation? x^2-2x-15 < 0 I don't understand why the answer (-3,5) does not include negative infinity or infinity in the answer
