Answer:
This can be solved by calculating a first degree Taylor approximation polynomial for the function in question around x=a. Taylor's first degree polynomial is given by:
Through this expression, which is easily evaluable around the point x = a, the function f (x) is approximated through a linear function.
Step-by-step explanation:
Answer: Last option.
Step-by-step explanation:
The equation of the line in slope-intercept form is:
Where m is the slope and b the intersection with the y-axis.
You can observe in the graph that the line passes through the origin, then:
Choose two points of the line and calculate the slope with:
Points: (2,3) and (-2,-3)
Substitute values, then the slope is:
Substituting "m" and "b" into , you get that the equation is:
This can be written as:
