Consider the function f(x). Select all of the following that include a vertical stretch of f(x)

zhenek [66]

Answer:

F , D, A

Step-by-step explanation:

As we know vertical stretch of f(x) happens when we chane the value of the patameter a in this general form:

y = a. f(k(x-d))+ c

when |a| > 1 because When |a| > 1 (when a is greater than 1), the function is stretched vertically by a dilation factor of |a|.

So we choose, F , D, A

Answer:

b= $\sqrt{21}$

Step-by-step explanation:

Considering the given figure the sides 'b' , '2' and '5' are making the sides of a right angled triangle in the top right corner of the square, where

Hypotenuse=5 , Perpendicular=b and Base=2

Using Pythagoras Theorem:

$(Hypotenuse)^2=(Perpendicular)^2+(Base)^2\\$

Implementing the values in the formula:

$5^2= b^2+2^2$

$b^2=5^2-2^2\\\\b^2=25-4\\\\b^2=21\\\\b=\sqrt{21}$

So, the value of 'b' is $\sqrt{21}$ which is same for the the given 'b' in the figure.
