We have been given a system of equations. and
. We are asked to find the solution of the equation
by sketching the functions.
We can see that f(x) is a linear function in slope-intercept form. The slope of f(x) is 1 and y-intercept at point .
We can also see that g(x) is a quadratic function. The function g(x) is an upward opening parabola, whose vertex is at point .
Upon graphing both equations, we will get our required graph as shown in the attachment.
The solution of will be the x-coordinates of points, where both functions will intersect.
We can see that both functions are intersecting at , therefore,
are the solutions of
and option B is the correct choice.
