Answer:
The correct option is C.
Step-by-step explanation:
The given cubic equation is

According to the rational root theorem 1 and -1 are possible rational roots of all polynomial.
At x=-1, the value of function 0. Therefore (x+1) is the factor of polynomial and -1 is a real root.
Use synthetic division to find the remaining polynomial.


Using 

USe zero product property and equate each factor equal to 0.

Therefore the equation have three real roots out of which the value of two roots are same.
Option C is correct.
1.) 1.67×10 to the power of 9
2.) 1.133×10 to the power of -3
3.) 1.75×10 to the power of 9
4.) 2.64×10 to the power of 4
5.) 2.947×10 to the power of -6
6.) 4.24×10 to the power of 5
7.) 1.0207×10 to the power of 6
8.) 1.027×10 to the power of 5
22382. You just multiply 1178 and 19 :-)
The y-intercept appears to be at y=-1. The line appears to also go through grid point (3, 1), which is 2 units up and 3 units over. The slope is 2/3.
In slope-intercept form the equation of the line is
y = (2/3)x - 1
13 1/4 is the answer
9 7/8 + 3 3/8
12 10/8
13 2/8
13 1/4 (simplified)
