Answer:
(1, -5) or x=1, y=-5
Step-by-step explanation:
Hope this helps!
A function is described as a quadratic function if the highest power of the variables of the function is 2.
For
The highest power of x is 1, hence, the function is not a quadratic function.
For
The highest power of a is 2, hence, the function is a quadratic function.
For
The highest power of y is 1, hence, the function is not a quadratic function.
For
The highest power of b is 2, hence, the function is a quadratic function.
Therefore, the quadratic functions are (4a + 2)(2a - 1) + 1 = 0 and <span>2b(b - 7) + b = 0</span>
The formula for direct variation is y = k × x and the formula for inverse variation is y = k/x
The direct variation represented by the equation
y ∝ x
Its is y directly proportional to x
Where x is the independent variable
y is the dependent variable
By replacing the ∝ sign with the equal sign. The equation will be
y = kx
Where k is the constant of proportionality
Similarly the inverse variation is
y ∝ 1/x
Replace the ∝ sign with the equal sign
y = k/x
Therefore, the direction variation represented by y = k × x and inverse variation represented by y = k/x
