3 main angles: Right; a right angle is 90 degrees, Obtuse; blunt more then 90 and less then 180, Acute: Less then 90.

Angles larger than a right angle and smaller than a straight angle (between 90° and 180°) are called obtuse angles ("obtuse" meaning "blunt"). An angle equal to 12 turn (180° or π radians) is called a straight angle.

HELP ME PLEASE!! is y=2x^2 - 4 linear or non linear

OleMash [197]

Answer:

non-linear

Step-by-step explanation:

Linear functions can only have powers of 1 for the x and y terms and the terms must not be multiplied.

The function y =2x^2-4 has a power of 2 on the x so it is not linear. It is parabolic.

please help! functions and relations. f(x)= square root of x-4. find the inverse of f(x) and it’s domain.

likoan [24]

ANSWER:

$\:D.\text{ }f^{-1}\left(x\right)=\left(x+4\right)^2;x\ge-4$

STEP-BY-STEP EXPLANATION:

We have the following equation:

$f(x)=\sqrt{x}-4$

The inverse is the following (we calculate it by replacing f(x) by x and x by f(x)):

$\begin{gathered} x=\sqrt{f^{-1}(x)}-4 \\ \\ \sqrt{f^{-1}(x)}=x+4 \\ \\ f^{-1}(x)=(x+4)^2 \end{gathered}$

The domain would be the range of the original equation, and it would be the range of values that f(x) could take, which was from -4 to positive infinity, that is, f(x) ≥ -4.

Therefore, the domain is x ≥ -4.

So the correct answer is D.

$\:f^{-1}\left(x\right)=\left(x+4\right)^2;x\ge -4$
