At what point(s) do these graphs intersect? y+x^2=3x-5 and y=4x+1 Seth’s solution:

y=x^2=3x-5

y=4x+1

x^2+3x-5=4x+1

x^2-x-6=0

x=3 and x=-2

The graphs intersect at (-2,0) and (3,0).

Is Seth’s solution correct? Explain.

Incorrect. Graphs do not intersect

Step-by-step explanation:

Solution:-

- We are given two equations for the each plot as follows:

- To determine the coordinates of intersection of the two plots we will use direct substitution of equation 2 into 1:

- Subtract ( 3x ) and add ( 5 ) on both sides of the equation above:

- To solve the quadratic equation we will use the quadratic formula:

- We see that the square root of a negative number is "undefined" or have "complex solution". In other words, the solution does not exist.

- The graphs do not intersect.
