Answer:
x=12
Step by step explanation:
If 2 + 5i is a zero, then by the complex conjugate root theorem, we must have its conjugate as a zero to have a polynomial containing real coefficients. Therefore, the zeros are -3, 2 + 5i, and 2 - 5i. We have three zeros so this is a degree 3 polynomial (n = 3).
f(x) has the equation
f(x) = (x+3)(x - (2 + 5i))(x - (2 - 5i))
If we expand this polynomial out, we get the simplest standard form
f(x) = x^3-x^2+17x+87
Therefore the answer to this question is f(x) = x^3-x^2+17x+87
Answer:
(9 1/2)/(4 3/4)
19/2)/19/4) Divide:
19*4/2*19= 76/38= 2 rooms
Step-by-step explanation:
Answer:
(a) The slope of f(x) is greater than the slope of g(x)
(b) f(x) has a greater y intercept
Step-by-step explanation:
Given


Solving (a): Compare the slopes
The slope (m) of f(x) is calculated as;

This gives:


Substitute values for f(0) and f(1)



The slope of g(x) can be gotten using the following comparison


So:



Solving (b): Compare the y intercept
y intercept is when 
From the table of f(x)

From the equation of g(x)
