When you multiply a function by -1, what is the effect on its graph?

The graph is reflected about x-axis.

Step-by-step explanation:

Since, rule of reflection across x-axis,

And, the rule of reflection across y-axis,

Thus, when a function f(x) is reflected across x-axis,

Then, the transformed function is -f(x),

While, when f(x) is reflected across y-axis,

The transformed function is -f(x),

Hence, we can say that,

When a function is multiplied by -1, it will reflect about x-axis.

step-by-step explanation:

idk the answer i want to say 10 but then it would be equal so try 9 but then yeah so yeah we love edgen

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
