F(x) = 3x^2 + 4x - 1

f(-3) = 3(-3)^2 + 4(-3) - 1

f(-3) = 3 * 9 - 12 - 1

f(-3) = 27 - 12 - 1

f(-3) = 15 - 1

f(-3) = 14

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.
