<h3>2 Answers: Choice C and choice D</h3>

y = csc(x) and y = sec(x)

==========================================================

Explanation:

The term "zeroes" in this case is the same as "roots" and "x intercepts". Any root is of the form (k, 0), where k is some real number. A root always occurs when y = 0.

Use GeoGebra, Desmos, or any graphing tool you prefer. If you graphed y = cos(x), you'll see that the curve crosses the x axis infinitely many times. Therefore, it has infinitely many roots. We can cross choice A off the list.

The same applies to...

  • y = cot(x)
  • y = sin(x)
  • y = tan(x)

So we can rule out choices B, E and F.

Only choice C and D have graphs that do not have any x intercepts at all.

------------

If you're curious why csc doesn't have any roots, consider the fact that

csc(x) = 1/sin(x)

and ask yourself "when is that fraction equal to zero?". The answer is "never" because the numerator is always 1, and the denominator cannot be zero. If the denominator were zero, then we'd have a division by zero error. So that's why csc(x) can't ever be zero. The same applies to sec(x) as well.

sec(x) = 1/cos(x)

Which statement best describes the effect of replacing the function f(x) = 2x − 2 with the function g(x) = 2x + 5? The graph shi
AlexFokin [52]

Original given function is f(x) = 2x − 2 and transformed function g(x) = 2x + 5.

Please see..

If we add 7 in f function, we get

f(x) = 2x − 2 +7 = 2x + 5 and that is the g function.

According to rules of transformation f(x)+c shift c units up and f(x)-c shift c units down.

We added 7 to f function.

<h2>Therefore, it is being shifted 7 units up.</h2><h3>Note: We are not given correct answer in given options.</h3>
