Answer:
Option A
Explanation:
From the graph given in the picture,
Function 1
Rate of change = Slope of the line
Slope of a line passing through two points
and
is,
Slope =
Therefore, slope of the given line which is passing through (1, 2) and (-1, -2)will be,
Rate of change =
= 2
Function 2
Equation of the line is,
y =
By comparing this equation with slope-intercept form of the equation,
y = mx + b
Here m = rate of change Or slope of the linear function
Rate of change of function 2 =
Therefore, rate of change of function 1 is higher than function 2.
Option A will be the answer.
