Graph y=x^2+1 is it a function

1 answer:

7 0

Hello,

The graph of y = x² + 1 most certainly is a function.
It is a function because for every value of x, there is only one value of y.

The domain of y = x² + 1 is the set of all real numbers and the range is y ≥ 1.

Answer:

x ≤ $\frac{19}{4}$

Step-by-step explanation:

Given

$\frac{x-1}{3}$ - 2 ≤ $\frac{5-2x}{6}$

Multiply through by 6 to clear the fractions

2(x - 1) - 12 ≤ 5 - 2x ← distribute and simplify left side

2x - 2 - 12 ≤ 5 - 2x

2x - 14 ≤ 5 - 2x ( add 2x to both sides )

4x - 14 ≤ 5 ( add 14 to both sides )

4x ≤ 19 ( divide both sides by 4 )

x ≤ $\frac{19}{4}$
