At which root does the graph of f(x) = (x – 5)3(x + 2)2 touch the x axis?

LuckyWell [14K]

We have that
f(x) = (x – 5)³(x + 2)²

we know that
<span>the roots can touch or cross the x axis

</span>The way you can tell if the graph is going to cross the x-axis or just touch the x-axis is by looking at the power of the factor.

(x - 5)³ has a power of 3 which is an ODD number. An ODD power means that the graph will cross through the x-axis.

(x + 2)² has a power of 2 which is an EVEN number. An EVEN power means that the graph will touch the x-axis.

therefore

the answer is
<span>the graph of f(x) touch the x axis for the root x=-2
</span>
see the attached figure

The function f(x) = 5()x is reflected over the y-axis. Which equations represent the reflected function? Check all that apply.

Taya2010 [7]

Key term "Reflected", which is equivalent to "inverse". This means that the graph, although remains with the same points, is "reflected". Think of a mirror.
Say y = m(x). The reflected result is y = -m(x). Or in another case, y = m(-x) will be reflected to y = m(x).
Lets break this rule further. Say your point was (a,b) which is code for (x,y). If we're looking at the x-axis, the y becomes negative. Henceforth, it becomes (x,-y) and vice versa.
In this case, we're looking at the y-axis reflected, meaning, the x-value will be NEGATIVE.

Answer is C: m(x) - 5() -x This can be seen as m(x) = m(-x) as well.

Jeff has some coins so he can put in 6 bags or 9 bags with no coins left but if put in 5 bags 2 coins left. So at least how many

sertanlavr [38]

Answer:

Step-by-step explanation:

Jeff can divide the coin evenly in 6 or 9 bags, so the number of coin should have 9 and 6 as the factor. The lowest common factor for 6 and 9 will be:

6= 2 x 3

9= 3^2

LCF= 2 x 3^2= 18

From here you need to find the common multiple of 18 that will have 2 remainder after divided by 5. When 18( divided by 5, it will left 3 as remainder.

Multiple of 3 that give 2 remainder after divided by 5 will be 3x4= 12. Then least coin Jeff should have will be: 4x18= 72
