The graph of a linear function passes through the point (2,5) and a slope of 3

Delicious77 [7]

Answer:

$y=3x-1$

Step-by-step explanation:

The point slope form of a line is $(y-y_1)=m(x-x_1)$ where $x_1=2\\y_1=5$ . We write

$(y-5)=3(x-2)$

Convert point slope form to slope intercept form by simplifying and rearranging.

$y-5=3(x-2)\\y-5=3x-6\\y=3x-1$

Let f(x) = x2 − 16. Find f−1(x)

Yanka [14]

Answer:

$f^{-1}(x)=\pm\sqrt{x+16}$

Step-by-step explanation:

$f(x)=x^2-16$

To find the inverse of this function, temporarily the f(x) with a y (or whatever else you want) and then solve for the x.

$y=x^2-16\\y+16=x^2\\x=\pm\sqrt{y+16}$

Now, you can swap the variables again and write the function.

$f^{-1}(x)=\pm\sqrt{x+16}$

What is the e at the end of a scientific number?

kherson [118]

Scientific notation is another way to write a number. In scientific notation, the letter E is used to mean "10 to the power of." For example, 1.314E+1 means 1.314 * 101 which is 13.14 .
