We see that the points of the graph of the function never attain a y-value of 0. Thus f is never equal to 0 for real numbers, hence we can disqualify all the necessary answers already (only answer not against this is 2). Nevertheless, we can show that this is the right answer. The graph is called a parabola, so it is represents a second order polynomial. These polynomials have either 2 real or 2 complex solutions. Since this does not have real solutions (at the lowest point of that polynomial the y-value is 4) the correct answer is b).

Part B

Answer:

if you are asking what the measure of the other angle is if it's just two angles and they are supplementary, the answer is 145º

Step-by-step explanation:

Supplementary angles would add up to equal 180º.

Angle W, which we already know is 35º.

Let's just call the other angle "x" for now.

1. Since we know the two angles will equal 180º, we can do x + 35= 180

2. Now we have the equation set up, and we can subtract 35 from each side

3. Once you subtract 35 from each side, you get x = 145º, which is your answer!
