Question

If the formula y = r is changed by adding one (shown in red below), what effect would that change have on the function's values? px) = 23+1 Select an answer What effect would it have on the graph? Select an answer

Answer 1

Given:

`y=x^3`
`f(x)=x^3+1`

From the given y = x³, it has changed to f(x) = x³ + 1

Adding a value to the y-intercept of a function will result for its graph to shift upward.

In this case, since we added 1 (+1) to the formula, this will add 1 to all the y values of the graph. Therefore for the first part of the question, the answer would be "It would add one to all the y-values"

Next, since we know that adding a y-intercept will move the graph upwards, the answer for the second part would be "It will shift all points up one."

To make it even more clearer, here is an example.

To conclude this, the answer to the first part would be ""It would add one to all the y-values"
