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

If a function f(x) multiplied by -1, the graph of f(x) reflect across x-axis.

Step-by-step explanation:

Let a function be f(x).

Multiply the function by -1 to get a new function g(x).

If a function is defined as , then the graph of function f(x) reflect across x-axis.

If a function is defined as , then the graph of function f(x) reflect across y-axis.

Since g(x)=-f(x), therefore the a function f(x) multiplied by -1, the graph of f(x) reflects across x-axis.

it’s supposed to be -4+45=41

step-by-step explanation:

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
