Solve the system y=x²-2 and x²+y=4.Illustrate graphically.

lawyer [7]

Answer:

Solution: $(-\sqrt{3},1),(\sqrt{3},1)$

Step-by-step explanation:

System of equation:

$y=x^2-2\text{ and }x^2+y=4$

Using substitution method.

$y=x^2-2$ substitute into $x^2+y=4$

$x^2+x^2-2=4$ (combine like term)

$2x^2=4+2$ (Addition property of equality)

$2x^2=6$ (division property of equality)

$x^2=3$ (Taking square root)

$x=\pm \sqrt{3}$

Substitute x into $y=x^2-2$

$y=(\sqrt{3})^2-2$

$y=1$

Solution: $(-\sqrt{3},1),(\sqrt{3},1)$

Now cross check the solution using graph.

If you knew that f(-4)=8, then what (x,y) coordinate point must lie on the graph of y=f(x)?

AysviL [449]

I believe it would be (-4, 8); because when x = -4, y = f(x) = 8.
