Using the given points, you can write the equation as ...
y=7.5\left(\dfrac{16.875}{7.5}\right)^{\frac{x-1}{3-1}}=7.5\cdot (2.25^{\frac{1}{2}})^{x-1}\\=7.5\cdot 1.5^{x-1}=7.5\cdot 1.5^{-1}\cdot 1.5^{x}\\y=5\times 1.5^{x}

shepuryov [24]
The correct answer is option C.

The solution is shown below:

(8 - 3i)(6 + 5i)

= 8(6 +5i) - 3i(6 + 5i)

= 48 + 40i - 18i - 15i²

= 22i + 48 - 15(-1)

= 22i + 48 + 15

= 22i + 63

= 63 + 22i

When looking at the graph of a 5th degree function, how can you determine if all of the zeros of the function are real?
Finger [1]

Answer:

If it cuts x-axis 5 times.

Step-by-step explanation:

When we look at the graph of a function we can see its real roots by looking at its graph

The intersecting points that is the number of times a line cutting x-axis will be the real root of the function

So, by looking at the 5th degree function the number of time that function cuts x-axis will be the number of real roots.

So, if we need to say all the zeroes or roots of the function are real means it will cut the x-axis 5 times.

Because a function will have the root equal to its degree.
