Solve the system of equations below by graphing. x^2-2x+y-3=0 x^2+y=0 what is the solution rounded to the nearest hundredth? (–2.25, –1.5) (–1.5, –2.25) (–0.82, –0.68) (–0.68, –0.82)

ANSWER

The correct answer is B

EXPLANATION

The first function is

We make y the subject to obtain;

Let us quickly write this in the vertex form.

Since the is negative, the graph opens up.

The vertex is at

The y-intercept is

The x-intercept is found by equating the function to zero.

With these information we can quickly sketch the graph as shown in the attachment(the red graph).

For the second function,

we again make y the subject to obtain,

This is a basic quadratic function that can be graphed easily. Note that it is also a maximum graph.

From the graph the solution to the two functions is

pakistan's principal natural resources are arable land and water. about 25% of pakistan's agriculture accounts for about 21% [1] of gdp and employs about 43% of the labour force. in pakistan, the most agricultural province is punjab where wheat and cotton are the most grown.
