Ms. F was showing her work to verify a question. She got that x = -3. In which step did she make her mistake while verifying the equation? (−5)x = 15
Step 1: (−5)(−3) = 15
Step 2: (−15) = 15

Sam claims that cos x =sin y if x and y are congruent angels. is sam correct ?

Which of the statements about the graph of the function y = 2x are true? check all of the boxes that apply. the domain is all real numbers x because the exponent of 2 can be any real number when the x-values increases by 1 unit, the y-value multiplies by 2. the y-intercept is (0, 1). the graph never goes below the x-axis because powers of 2 are never negative. the range is all real numbers.

For f(x) = 3x+1 and g(x) = x2 - 6, find (g/f)(x)
