Question

Identify the type of function represented by each equation.
y= 3[x]
y= 3x^2
y=2.5x
y=-1.5
y= 4/x
are they
Greatest Integer, Joint ,Quadratic, Inverse Variation ,Constant, Direct Variation
please help

Answer 1

First is greatest integer

Answer 2

great, quadratic, direct, constant, inverse

Answer 3

a quadratic has the variable raised to the second power

Answer 4

constant has no variable

Answer 5

inverse has the variable in the denominator

Answer 6

1. [x] represents the Greatest Integer, so first one is Greatest Integer..

2. \(x^2\) means degree = 2, Polynomials having degree 2 are called Quadratic..

3. y = 2.5x Here as Y increases or decreases similarly x increases or decreases, so this function is called Direct Variation..

4. y = -1.5, here -1.5 is constant, So This is constant..

5. \(y = \frac{4}{x}\) , here as y increases then x decreases and vice-versa, so this is inverse variation..
