Step-by-step explanation:

is it x*2 or x^2?

in the function y-1=1/2(x-6)^2 what effect does the number 6 have on the graph, as compared to the graph y=x^2
butalik [34]

Answer: The graph is shifted 6 units to the right.

Step-by-step explanation:

It is important to remember that:

When f(x-k), then the function is shifted "k" units to the right.

Knowing this and given the quadratic parent function y=x^2 and the function y-1=\frac{1}{2}(x-6)^2, you can observe that one of the transformations is the following:

f(x-k)

Where:

k=6

Therefore, you can notice that the effect is:

The graph is shifted 6 units to the right.

If f(c)=0, which of the following statements must be true?
Tju [1.3M]

Answer:

C.

Step-by-step explanation:

If f(c)=0 then (c,0) is on the graph.

In general, if f(a)=b then (a,b) is on the graph.

By factor theorem if f(c)=0 then x-c is a factor.

If x-c is a factor then x-c will divide f(x) evenly.  We know this because the remainder will be 0 because we know x-c is a factor of f.

The only choice that I have said in this whole thing that is true is C.
