What is the inverse of the function y= x^2-12

aalyn [17]

Answer:

$y=\sqrt{x+12}$

Step-by-step explanation:

To find the inverse of a function, what I like to do is to switch the places of x and y, and then try to isolate y again like so:

$x=y^2-12$

$x+12=y^2$

$y=\sqrt{x+12}$

Hope this helps!

????????!1!!!!!!! HELPPPPPPPPPPP

pav-90 [236]

Answer:

Step-by-step explanation:

Let us say, Olivia's age is x.

Now as the question says, we will get this equation.

$( \frac{1}{3} x ) + 12= 2x - 3$

Multiply both sides by 3.

$x + 36 = 6x - 9$

Collect like terms.

$x - 6x = - 9 - 36$

Calculate.

$- 5x = - 45$

Divide both sides of the equation by -5.

$x = 9$

Then, we will get the answer.

I hope it helps.

Write the equation of the line through each point.

Leya [2.2K]

Answer:

The equation would be y = -1/3x + 4

Step-by-step explanation:

The first step to finding this equation needs to be solving the first equation for y so that we can find the slope.

-3x + y = 1

y = 3x + 1

Now that we have the slope of 3, we know the slope of a perpendicular line would be -1/3. This is because perpendicular lines have opposite and reciprocal slopes. We can then use this and the point to solve in point-slope form.

y - y1 = m(x - x1)

y - 2 = -1/3(x - 6)

y - 2 = -1/3x + 2

y = -1/3x + 4

Which property does each equation demonstrate? x2 + 2x = 2x + x2 (3z4 + 2z3) – (2z4 + z3) = z4 + z3 (2x2 + 7x) + (2y2 + 6y) = (2

Answer:

1 . Closure

2. Distributive

3. Closure

Step-by-step explanation:

Here, we want to know the type of property exhibited or displayed by each of the equations in the question.

Equation 1 displays the closure property.

What this means that if we make an addition operation either way, we would get same answer. So we say that addition is closed for that equation.

Equation 3 exhibits closure property as well. If we go either way on the addition operation for that equation, we are bound to get the same answer.

Equation 2 exhibits the distributive property.

Each term in the bracket is multiplied by the subtraction symbol before we proceeded to complete the arithmetic operations
