Using the zero function in calculate will get you to the answer of x=1.696. 1.969 is between 1 and 2. ||  || Correct || a negative. If it were translating to the left, it would be positive. ||  || Correct || -1 raised to 3 is -1, multiplied by 2 is -2. Add to 5 to get 3. ||  || Correct || at the powers on the factors. The problem asks for the multiplicity when x=2. The only way to get a zero with x=2 is to plug it into the first factor of (x-2). The power over this factor is 2. The multiplicity is 2. ||  || Correct || 3rd power graph, so C is out. The graph crosses the zeros bcause they're open, both times, so D and E are out. Then I looked at how the first zero would be -2 and the second would be 2. ||  || Correct || zero, and an open zero at 2. B doesn't have the same picture as A because B is the opposite of A. Simplified out, the leading coefficient would be negative in B, and the graph is not negative. ||  || Correct - Well Done Gentlemen! ||
