What is the discontinuity and zero of the function f(x) = 3x^2 + x - 4 / x-1 question 3 options: 1) discontinuity at (1, 7), zero at ( negtive four thirds , 0) 2) discontinuity at (−1, 1), zero at ( negative four thirds , 0) 3) discontinuity at (1, 7), zero at ( four thirds , 0) 4) discontinuity at (−1, 1), zero at ( four thirds , 0)

for the first question it would be the second answer for the second question it would be the third answer and for the third question it would be the first answer

step-by-step explanation:

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
