The graph of y = x^3 is transformed as shown in the graph below. Which equation represents the transformed function?
Kay [80]

Answer:

y = -6 * x^3

Step-by-step explanation:

We can model the new function as:

f(x) = ax^3

the function y = x^3 have positive values of y for positive values of x, and negative values of y for negative values of x.

As the negative values of x have positive values of y and vice-versa, the first change is to put a negative sign in front of x^3, so we know that 'a' is negative.

Then, for x=1 we have y = -6, so:

-6 = a*1^3

a = -6

So the equation of the transformed function is:

y = -6 * x^3

Evaluate if x =3 and y = -2<br><br> x2+2xy−4y
Marysya12 [62]

Answer:

5

Step-by-step explanation:

With the equation x^2 + 2xy - 4y, we can substitute the values of x = 3 and y = -2 into the equation to find its result.

(3^2) + (2\cdot3\cdot-2) - (4\cdot-2)\\\\9 + (6\cdot-2) - (-8)\\9 - 12 + 8\\5

Hope this helped!
