How to find amplitude and period from equation?

polet [3.4K]

If your graph is a COS or SIN graph :

$y = a \sin(bx) + c$
a is the Amplitude
and period is:
$\frac{360}{b}$

If your graph is a TAN graph :
$y = a \tan(bx) + c$
A TAN graph has no amplitude as it has no Maximum or Minimum value.
To find period :
$\frac{180}{b}$

Match each polynomial function with one of its factors.

insens350 [35]

Ex.
$2 {x}^{4} + 8 {x}^{3} + 4 {x}^{2} + 2 {x}^{2}$
This would be

$2 {x}^{2} ( {x }^{2} + 4x)(2 + 1)$

How?

Group them
$(2 {x}^{4 } + 8 {x}^{3} )(4 {x}^{2} + 2 {x}^{2} )$

Make sure there is a GCF.
$2 {x}^{2} ( { x}^{2} + 4x)(2 + 1)$

Hope this was clear

Answer:

y=-2/3x+6

Step-by-step explanation:

y-y1=m(x-x1)

y-4=-2/3(x-3)

y=-2/3x+6/3+4

y=-2/3x+2+4

y=-2/3x+6
