Question

The question is Based on the partial set of values given for a function, identify which description best fits the function.

Answer 1

A) This is a linear function and the equation of the graph is conventionally y = mx + c where m is gradient and c is intercept on y axis

In this function, the equation of the graph is

y = 4x + 1

B) This is a quadratic function and it takes the form:

$ax^2+bx+c$

where a = -1, b = 4 and c = -2. Thus the equation of this line is:

$-x^2+4x-2$

C) This is an exponential function. The c(x) value increases with the increasing powers of 3.
