Find the Domain and Range y=x^4-4x^3+14/3x^2-9/7x+2

$y = x^{4} - 4 x^{3} + \frac{14}{3} x^{2} - \frac{9}{7} x + 2$

Step 1

The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined.

Interval Notation:

$(- \infty, \infty)$

Set-Builder Notation:

${x | x \in ℝ}$

Step 2

The range is the set of all valid $y$ values. Use the graph to find the range.

Interval Notation:

$[1.89741683, \infty)$

Set-Builder Notation:

${y | y \geq 1.89741683}$

Step 3

Determine the domain and range.

Domain: $(- \infty, \infty), {x | x \in ℝ}$

Range: $[1.89741683, \infty), {y | y \geq 1.89741683}$

Step 4

Find the Domain and Range y=x^4-4x^3+14/3x^2-9/7x+2
