Given the following rational function: R(X) = X X2 - 4 State the Domain of R(x) in interval notation in the space below. Your answer should be submitted with no spaces between any characters. Use the expression "inf" to mean infinity. For example, if you were wanting to represent two separate intervals, one which included the numbers from 0 to 5, and another which included the numbers from 8 to positive infinity you would submit your answer as: [0,5]U[8,+Inf). You must indicate -inf versus +inf to be graded correctly for this question. QUESTION 2 Given the following radical function: P(t) = 2 2t +8 -5 State the Domain of P(t) in interval notation in the space below. Your answer should be submitted with no spaces between any characters. Use the expression "inf" to mean infinity. For example, if you were wanting to represent the set of all real numbers you would submit your answer as: (-inf,+inf). You must indicate -Inf versus +inf to be graded correctly for this question. QUESTION 3 For the following radical function, find the coordinates of the P and t intercept. P(t) =3V25 -2t -9 Your answer should be submitted with no spaces between any characters. For example, if one of the intercepts was the origin, you would submit your answer as: (0,0) P-int = t-int = QUESTION 4
