Determine the different possibilities for the numbers of positive, negative, and nonreal complex zeros for the following function.
f(x) = 4x^3 - 5x^2 + 4x + 9
What is the possible number of positive real zeros of this function?
(Use a comma to separate answers as needed.)
What is the possible number of negative real zeros of this function?
(Use a comma to separate answers as needed.)
What is the possible number of nonreal complex zeros?
(Use a comma to separate answers as needed.)

the answer is a

step-by-step explanation:

constants mean the stopped points or the points on a graph that nothing is changing, hope this

step-by-step explanation:

, and

for

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be

, and for

60°

step-by-step explanation:

the measure angle of c in an isosceles triangle abc is 60° because in isosceles triangle,the measures of all the angles is 60°.
