which graph represents f(x)= -1/3x^3? explain how you based on the sign of the leading coefficient and degree of function.

3rd

Step-by-step explanation:

Negative suggests that whatver the graph is, it's the opposite of the original function. That leaves us with 2 and 3 (since 1st one is positive x^3 )

Now, the degree 3 tells you that it has to be number3 because that's the 3rd degree graph, Since second one is a upside down parabola which means -x^2

Hope this cleared things up for you!

Step-by-step explanation:

All you have to do is pick the graph that comes down from the left to the right because the cubic function is negative. This would be a the third graph.

(0,-3) see attached graph

step-by-step explanation:

a. to solve the system, graph the two equations.

x = y+3 becomes y=x-3 has m=1/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move up 1 unit and 1 unit to the right. plot a point and connect.

y=-4x+3 has m =-4/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move down four units and to the right 1 unit. plot a point and connect.

the solution is the point (x,y) where the two lines intersect. by the graph below it is (0,-3).

b. to solve by substitution, substitute y = -4x-3 into x= y+3

x= (-4x-3) +3

x=-4x

5x=0

x=0

now substitute x = 0 back in to find y.

y= -4(0)-3

y=0-3

y=-3

solution is (0,-3)

c. use elimination by adding the equations together.

x-y=3

4x+y=-3

5x=0

x=0

then substitute into one equation to find y.

y=-4(0)-3

y=-3
