In Problems 87鈥�94, analyze each polynomial function f by following Steps 1 through 8 on page 192.
$f (x) = - 1.2 x^{4} + 0.5 x^{2} - \sqrt{3} x + 2$

Short Answer

Expert verified

$f (x) = - 1.2 x^{4} + 0.5 x^{2} - \sqrt{3} x + 2$

Step by step solution

Step 1. Given Information

$f (x) = - 1.2 x^{4} + 0.5 x^{2} - \sqrt{3} x + 2$

Step 2. End Behavior

$f (x) = - 1.2 x^{4} + 0.5 x^{2} - \sqrt{3} x + 2$

Since as $x 鈫� - 鈭�$ then $f (x) 鈫� - 鈭�$

and as $x 鈫� 鈭�$ then $f (x) 鈫� - 鈭�$

Step 2. Graph

Step 3. x and y-intercept

$f (x) = - 1.2 x^{4} + 0.5 x^{2} - \sqrt{3} x + 2$

Then, $f (0) = 2$

For x-intercept

$- 1.2 x^{4} + 0.5 x^{2} - \sqrt{3} x + 2 = 0$

Solving this we get, $x = - 1.472, 0.913$

Therefore, $x -$ intercept is $(- 1.472, 0) & (0.913, 0)$

and $y -$ intercept is $(0, 2)$ .

Step 4. Calculation

Now we have to find points about the point of the graph.

$x$	$y$
$- 2$
$- 1$
