Answer:

Scientists think the smallest black holes formed when the universe began.

Stellar black holes are made when the center of a very big star falls in upon itself, or collapses. When this happens, it causes a supernova. A supernova is an exploding star that blasts part of the star into space.

Scientists think super-massive black holes were made at the same time as the galaxy they are in.

Analyze the zeros of f(x)=^4-3x^3-2x^2+3x-5
spayn [35]

Answer:

d.−1.4, 3.4

Explanation:

Given

f(x) = x^4-3x^3-2x^2+3x-5

Required

Determine the zeros

The best way to solve this is to apply the graphical method.

First, we plot the graph of: f(x) = x^4-3x^3-2x^2+3x-5

<em>See attachment </em>

Next, we write out all values of x when the line crosses the y-axis.

From the attached graph, the points are (approximately):

x =-1.449

x = 3.449

Option (d) is the closest to the above values.

<em>Hence, the zeros are: -1.4 and 3.4</em>
