What is the discontinuity and zero of the function f(x)= 2x2+5x-12/x+4

Option A.

Step-by-step explanation:

The given function is f(x) =

If denominator of the fraction is zero then the function will be discontinued.

In other words at (x + 4) = 0 the given function will be discontinued.

x = -4 will be the point of discontinuity

Now we will find the factors of numerator to find the zeros of the function.

2x² + 5x - 12 = 2x² + 8x - 3x - 12

                    = 2x(x + 4) - 3(x + 4)

                    = (x + 4)(2x - 3)

Now these factors (x + 4) = 0 and (2x -3) are the zero factors of the function.

Therefore, x = will be the zero of the function.

In option A x = -4 is the point of discontinuity and (, 0) is the zero of the function.

Option A will be the correct option.

the number of the people going.

step-by-step explanation:

the cost to buy one movie ticket is $7. if the total cost for the movie is a function of how many people go, then the input is : the number of the people going.
