4) Tyler is simplifying the expression 6 - 2x + 5 + 4x. Here is his work: step 1: (6 - 2)x + (5+4)x

step 2: 4x + 9x

step 3: 13x

A) He makes an error on step number .

B) Simplify the expression correctly and write the answer here:

A) find the derivative of the inverse to f(x) = 3x + sint at x 6. b) (cale) find the derivative of the inverse to f(x)+3sin at x 6. if x +2y -34, ind he behaviar of the cure at 4,.3), c) a. increasing, concave up d. decreasing, concave down b. increasing, concave down e. decreasing, inflection point c. decreasing, concave up
