Step-by-step explanation:

We have to make x the subject:

y = x² + 4x + 4.

=> y = (x + 2)² by completing the square

=> x + 2 = ±√y

=> x = ±√y - 2

Therefore the inverse is y = ±√x - 2.

Which statement is true? A dilation is not a function because a point on the pre-image could be mapped to more than one point on

lianna [129]

D) A dilation is a function because every point on the pre-image corresponds to exactly one point on the image.

Definition of Dilation

Dilation stretches or shrinks the original figure. Each pre-image point has exactly one point on the image which multiplied or reduced the scale factor.

Given that y(t)=c1e4t+c2e−4ty(t)=c1e4t+c2e−4t is a solution to the differential equation y′′−16y=0y′′−16y=0, where c1c1 and c2c2

tekilochka [14]

Solution :- Given differential equation

$y′′−16y=0$

So the characteristic equation will be

$r^{2} -16=0 ⇒r^{2} =16 ⇒[tex]r_{1}=4 \\or \\ r_{2}=-4$

so, the required function will be

$y=c_{1}e^{r_{1}t}+c_{1}e^{r_{2}t}$

⇒ $y=c_{1}e^{4t}+c_{1}e^{-4t}$ ia solution of the given differential equation

where $c_{1} \\and \\c_{2}$ are constants.
