Answer 1

Answer:

F. I only

Step-by-step explanation:

The c term in a quadratic equation as shown in the given example represents what the h value equals when t is 0, which would be the h-intercept. If you were to insert 0 for t in the entire equation, you would always get c as your answer since it's the only variable not multiplied by t in the equation. So if you change c, the only thing that will change is the h-intercept.

Hope this helps.

Answer 2

The alteration has an effect on (K) I, II and III

The function is given as:

$h = -at^2 + bt + c$

When the constant term (c) is altered, i.e. changed, the function becomes a different function entirely.

Take for instance, the new function is:

$h = -at^2 + bt + c+ 1$

The functions $h = -at^2 + bt + c$ and $h = -at^2 + bt + c+ 1$ are different, and both functions will have different intercepts and vertices.

Hence, the alteration has an effect on (K) I, II and III
