Solve using the quadratic formula x2 - 6x - 40=0 Question options: x = 10 or x = -4 x = 4 or x = -10 x = -7 or x = 7 x = -4 - √7

Crazy boy [7]

Answer:

$x=-10$ or $x=4$

Step-by-step explanation:

$ax^2+bx+c=0$

$x^2-6x-40=0$

$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$

$x=\frac{-6\pm\sqrt{6^2-4(1)(-40)}}{2(1)}$

$x=\frac{-6\pm\sqrt{36+160}}{2}$

$x=\frac{-6\pm\sqrt{196}}{2}$

$x=\frac{-6\pm14}{2}$

$x=-3\pm7$

$x=-10$ or $x=4$

What are the domain and range of the function below

Alina [70]

Answer:

<u>domain</u>: all real numbers

<u>range</u>: all real numbers greater than -2

Step-by-step explanation:

The domain is all the possible numbers that x, or the inputs to the function, can be. It looks like this function goes on forever both left and right, so its domain is all real numbers.

The range is all the possible numbers that y, or the outputs to the function, can be. It looks like this function starts growing at a y-value of -2 and then goes on forever, so its range is all real numbers greater than -2.

Hopefully that was helpful! :)
