8. B) sometimes true

9. A) always true

10. A) always true

Step-by-step explanation:

8. A polynomial function with real coefficients has real zeros. This is sometimes true because say we have an equation x^2+10. If you graph this, you will notice that there are no points on the x axis, or no zeroes. That means that this equation would have complex roots. x^2+10 is a real number equation without any complex numbers so the answer is sometimes true.

9. A polynomial function that does not intercept the x-axis has complex roots only. a If a line crosses or touches the x (horizontal) axis on a graph then you can say that the point where it touches is a root. If any equation on a graph does not have a point on the x axis then it has complex roots. So the answer is always true.

10. An odd degree polynomial function with real coefficients has at least one real root. a Think about all the odd degree equations you know. y=x^1 (basically y=x), y=x^3, etc. A linear slope intercept form equation has an odd degree of 1 and passes through the x axis only once. If you plug in x^3 on a graphing calculator or desmos.com/calculator you will see that the y range has infinately many solutions. You can mess with this and plug in whacky equations like x^3-42x^2+16.92x-.4^8; no matter what, there will always be atleast 1 real root, so this is always true.
