Solve each equation by graphing. round to the nearest tenth. x^2+6=-7x
a. 0,-7
b. -6,-1
c. 6,1
d. 1,6

Step-by-step explanation:

Given :

To Find: Solve each equation by graphing.

Solution:

Refer the attached figure.

Thus the values of x are -1,-6

So, Option B is correct.

Hence the values of x are -1,-6

First locate the turning point (vertex) of the graph. which is at the coordinates x=5 and y=9 or (5; 9).to determine whether it's a maximum or mininum value, you have to discern whether the vertex's y-value is the highest value or lowest value the graph can reach. since the vertex's y-value, 9 is the highest value the graph can reach, it will be a maximum.another basic way to determine whether the vertex's value is max or min is to see if the graph is smiling or sad. if it's smiling, the turning point/vertex would be a minimum, while a sad parabola would have a maximum y-value at the vertex.
