Find all zeros of ƒ(x) = 2x^4 – 72x^2. Then determine the multiplicity at each zero. State whether the graph will touch or cross

AleksandrR [38]

Answer: See below

Step-by-step explanation:

To find the factor,

f(x) = 0

$\begin{aligned}&2 x^{4}-72 x^{2}=0 \\&2 x^{2}\left(x^{2}-36\right)=0 \\&x^{2}\left(x^{2}-36\right)=0 \\&x \times x \times(x-6) \times(x+6)=0 \\&\mathrm{x}=0,0,6,-6\end{aligned}$

So,

x = 0 multiplicity 2

x = -6 multiplicity 1

x = 6 multiplicity 1

For an even multiplicty, the graph touches the x-axis, and for an odd multiplicty, the graph crosses the x-axis

Therefore,

x = 0 multiplicty 2, Touch

x = -6 multiplicty 1, Cross

x = 6 multiplicty 1, Cross

What is the slope of the line through (- 1, - 7) and (3, 9) ?

Fynjy0 [20]

Answer:

C. 4

Step-by-step explanation:

Use the slope formula:

$m=\frac{y2}{x2} -\frac{y1}{x1}$

m = the slope.

Substitute the values into the formula:

$\frac{9}{3} -\frac{-7}{-1} =\frac{?}{?}$

Solve:

$\frac{9}{3} -\frac{-7}{-1} =\frac{16}{4}$

Simplify 16/4:

$\frac{16/4}{4/4} =\frac{4}{1}=4$
