The domain of the function is given by the expression in alternative B
Step-by-step explanation:
The domain of a function is defined as the set of x-values for which the function is real and defined. For the given rational function, the function will not be defined if the function in the denominator assumes a value of zero.Therefore, the function will not be defined whenever; x(x^2-49)=0. Solving for x yields; x=0 and x=±7. This implies that the domain of the rational function is the set of all real numbers except where x=0 and x=±7. These are points of discontinuity
First tossing a coin means the first has to be H or T. Rolling a die means the second has to be a 1-6. The only option that meets this criteria is LETTER A
We would know the distance if information on the points C and D are given. As it is, there is no information. Please post an image, or coordinates of C & D.
