Answer:
x=-1,-3,2i and -2i
Step-by-step explanation:
By plugging in x=-1, f(x)=0 and x=-3,f(x)=0
That means x+1 and x+3 are roots of the fourth degree polynomial.
(x+1)(x+3)=x²+4x+3
Divide the polynomial by x²+4x+3 and that gives x²+4.
We now find the zeros of the factors
(x²+4x+3)(x²+4)=0
x=-1,-3,2i and -2i
Answer:
M is the slope of the equation and basically the constant rate of change. So when there are two given points, the slope of the line between them will equal m.
B is the y-intercept. The "starting point" on the y-axis.
Y is the dependant variable and the unknown that the equation solves for.
X is the independant variable, the input.
To plot an equation, plug in random x values which solves for y. After plotting 2 or more points, you can simply connect them with a line. If it's not a straight line, some of your points are wrong.
