What is the amplitude of the function?

Licemer1 [7]

Answer:

Step-by-step explanation:

Take the absolute value of the lowest y value.

$| - 1| = 1$

Take the absolute value of highest y value.

$|3| = 3$

Add those two together and divide by two.

$\frac{1 + 3}{2} = 2$

So the amplitude is 2

Simplify the Expression. [4 + (-8)] x (-7) A.) -84 B.) -28 C.) 28 D.) 84

Helen [10]

C. 28 is the answer
Staring from the brackets we have 4+(-8) we can open the parentheses and get 4-8 and get -4. Now we can open the -7 up and now we have
-4 * -7 = 28
Hope this helps!

Soln,

here

$9 {x}^{2} - 16$

$= ( {3x)}^{2} - {4}^{2}$

$= (3x + 4)(3x - 4)$
I hope this was helpful.

Answer:

= $6x^{2}$ −7x−20

Step-by-step explanation:

(2x−5)(3x+4)

= (2x+−5)(3x+4)

= (2x)(3x)+(2x)(4)+(−5)(3x)+(−5)(4)

= $6x^{2}$ +8x−15x−20

= $6x^{2}$ −7x−20
