Answer 1

Answer:

$g(x)=0.5x^2+x+4$

Solution: x=-2

Step-by-step explanation:

Consider the equation $-x^3-4=0.5x^2+x+4.$ Plot the graphs of left and right side functions $f(x)=-x^3-4$ and $g(x)=0.5x^2+x+4$ as shown in the diagram. The solution of the equation is the x-coordinate of the point of intersection between those two graphs. As you can see these graphs intersect at point (-2,4), thus, the solution of the equation is x=-2.

Answer 2

Answer:

Solution is (-2,4).

Step-by-step explanation:

We have given two equations.

f(x) = -x³-4 and g(x)  =  0.5x²+x+4

We have to find the solution of above equations when  -x³-4  =  0.5x²+x+4

We used method of graphing to find the solution of given equations.

In graphing, the solution of two equations is intersecting points.

Hence, the intersecting point of given equation is (-2,4).

Hence, solution is (-2,4).
