Given the quantity of 2 x squared plus 5 x minus 12, all over x plus 4, what are the domain and range? domain is x is all real numbers where x does not equal negative 4 comma range is y is all real numbers where y does not equal negative 11 domain is x is all real numbers where x does not equal 4 comma range is y is all real numbers where y does not equal 11 domain is x is all real numbers where x does not equal negative 4 comma range is y is all real numbers where y does not equal 5 domain is x is all real numbers where x does not equal 4 comma range is y is all real numbers where y does not equal negative 5

Answers

  1. Domain is all real numbers where x does not equal negative 4 comma range is all real numbers where y does not equal negative 11.

    What is the domain of a function?

    The domain refers to the values for which the function is defined. In this case we can properly write the function as;
    f(x) = 2x^2 + 5x – 12/ x + 4
    Now, given the fact that the domain has to be all the points where the function is continuous and the denominator is non zero we can say that the domain of the function is all real numbers where the x is not -4.
    Thus we have that; domain is all real numbers where x does not equal negative 4 comma range is all real numbers where y does not equal negative 11.
