How does the graph of g(x) = x + 4 compare with the graph of the parent function, f(x) = x?A. The graph of g(x) is compressed vertically by a factor of 4.B. The graph of g(x) is shifted 4 units up.C. The graph of g(x) is shifted 4 units to the right.D. The graph of g(x) is compressed horizontally by a factor of 4.

The answer is B. the graph of g (x) is shifted 4 units up.

The increase in a person's body temperature T(t), above 98.6ºF, can be modeled by the function T(t)=(4t)/(t^2 +1), where t represents time elapsed. What is the meaning of the horizontal asymptote for this function? The horizontal asymptote of y = 0 means that the person's temperature will approach 98.6ºF as time elapses. The horizontal asymptote of y = 0 means that the person's temperature will approach 0ºF as time elapses. The horizontal asymptote of y = 4 means that the person's temperature will approach 102.6ºF as time elapses. The horizontal asymptote of y = 4 means that the person's temperature will approach 4ºF as time elapses.

The person's body temperature will approach 98.6ºF as time lapses. Option A is correct.

How can Ari simplify the following expression? StartFraction 5 Over a minus 3 EndFraction minus 4 divided by 2 + StartFraction 1 Over a minus 3 EndFraction Write the numerator and denominator with a common denominator. Then divide the numerator by the denominator. To do this, multiply the numerator by the reciprocal of the denominator. Write the numerator and denominator with a common denominator. Then divide the numerator by the denominator. To do this, multiply the numerators and multiply the denominators. Divide the numerator and the denominator by a - 3. Then divide the numerator by the denominator. Divide the numerator and the denominator by a - 3. Then simplify the numerator and simplify the denominator

Which graph represents the function f (x) = StartFraction 4 Over x EndFraction?

B. Therefore, the graph of x = 0 is a vertical asymptote.A. on a coordinate plane, a hyperbola is shown. A curve opens up and to the right in quadrant 1, and another curve opens down and to the left in quadrant 3. A vertical asymptote is at x = 0.

Mr. knotts found the difference of the following expression. Which statement is true about Mr. Knotts work? x/x^2-1-1/x-1

C. HE DIDNT DISTRIBUTE THE NEGATIVE SIGN WHEN HE SUBTRACTED

Does the expression x^3-1/x^2-1 simplify to x?No, because x3 - 1 can be factored as x(x2 - x + 1) and x2 - 1 can be factored as x(x - 1), so only x can be canceled.Yes, because x3(x - 1) can be factored as x2(x - 1) and x2 - 1 can be factored as x(x - 1), so (x - 1) can be canceled.No, because the -1 in the numerator and denominator is not a common factor and cannot be canceled.Yes, because -1 in the numerator and denominator is a common factor and can be canceled.

C. No, because the -1 in the numerator and denominator is not a common factor and cannot be canceled
