Question 2
Note: Let t = theta since I there is no theta symbol on my keyboard.
(0, -1) = (cos t, sin t)
cos t = 0
sin t = -1
I read the answer from the given point.
On the unit circle, the point (0, -1) lies at 3pi/2. So, angle theta is 3pi/2.
tan t = sin t/cos t
tan t = cos t ÷ sin t
Therefore, tan t = what?
You finish....

Answer:
(3,0), (4,0), (5,0)
on the x-axis at 3, 4 and 5
Step-by-step explanation:
This function is a lovely swoopey cubic curve. If we finish factoring it, it's not to hard to see the x-intercepts. You set it equal to zero and solve it. The solutions are the x-intercepts (are the "zeros")
0=(x-5)(x^2-7x+12)
0=(x-5)(x-3)(x-4)
0=x-5, 0=x-3 & 0=x-4
x=5, x=3, x=4
This is where the graph crosses the x-axis.
