Need helping showing step by step answer to solve for f.
Alex73 [517]
You cannot "solve for f" here.  However, you can find the zeros/roots of f.  Set f = to 0.  Then, one by one, set each of the factors = to 0 and solve for x:

x+1=0 results in x=-1; x-5=0 results in x=5, and so on.

Thus, the solutions of f(x)=0 are {-1, 5, -3, 4, 8}

i need to know how to find the x and y intercepts and then graph the linear equation for the problem x+y=2
gizmo_the_mogwai [7]

Answer:

The x-intercept of the straight line is at (2,0) and the y-intercept is at (0,2).

Join those two points with a straight line and get the graph.

Step-by-step explanation:

The intercept form of a straight line equation is \frac{x}{a} + \frac{y}{b} = 1, where the x-intercept of the line is at (a,0) and the y-intercept will be at (0,b).

So, we have to arrange the equation of a straight line in the intercept form and then we can easily find the x-intercept and y-intercept of the line.

Given equation is x + y = 2

⇒ \frac{x}{2} + \frac{y}{2} = 1

Therefore, the x-intercept of the straight line is at (2,0) and the y-intercept is at (0,2).

Now, locate the two points as obtained on the graph and join them with a straight line and you will get the graph of the line. (Answer)
