Answer:
<em>y=-6</em>
Step-by-step explanation:
<u>Proportions</u>
A direct proportion is a relation between variables where their ratio is a constant value. This means that if y and x are proportional, then:
y = kx
Where k is the constant of proportionality.
Substituting x=-3 y=9:
9 = k(-3)
Now the relationship is:
y = -3x
For x=2
y = -3(2) = -6
Answer:
Step-by-step explanation:
We want to rewrite
in vertex form.
We factor 4 to get:
We add and subtract half the square of the coefficient of x.
We factor perfect square trinomial to get:
The equation that is given in this item can be mathematically expressed as,
f(x) = (x/7)^(1/3) - 9
The expression f(x) can be replaced with y such that the equation can also be written as,
y = (x/7)^(1/3) - 9
The first thing that needs to be done to get the inverse of the function is to interchange the positions of x and y. In this equation, that becomes,
x = (y/7)^(1/3) - 9
Then, solve for the value of y in terms of x.
Transpose the constant to the other side of the equation.
x + 9 = (y/7)^(1/3)
Raise the whole equation by 3 in order to eliminate the radical.
(x+9)³ = (y/7)
Multiply the equation by 7 to eliminate the fraction.
(x+9)³(7) = y
Thus, the inverse of the function is equal to
<em> f⁻¹(x) = 7(x+9)³
