Function A is represented by the equation y = 4x+6. Function B is a linear function that goes through the points shown in the
table.
x 1 3 4 6
y 3 9 12 18
Which statement correctly compares the rates of change of the two
functions?
O A. The rate of change of function A is 6.
The rate of change of function B is 3.
O B. The rate of change of function A is 4.
The rate of change of function Bis 6.
O C. The rate of change of function A is 6.
The rate of change of function B is 6.
O D. The rate of change of function A is 4.
The rate of change of function B is 3.

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.

step-by-step explanation:

vertical asymptote .

horizontal asymptote .

step-by-step explanation:

given function is .

vertical asymptote is given by setting

denominator =0

when degree of numerator and denominator are same then divide first term of numerator by first term of denominator to get horizontal asymptote.
