Answer:

-9

Step-by-step explanation:

The problem can be easily solved if you know your cube table. Because by knowing that, you know that 9³ is 729, meaning that -9³ would be -729.

Without knowing your cube tables, you can do -9 x -9 x -9 = -729.

Since -9 x -9 = 81, you can use a calcuator or solve on paper for 81 x -729.

Find f (2b^2) for (x)=x^2-4x

BlackZzzverrR [31]

Answer:

Step-by-step explanation:

We are given the function:

$f(x) = x^2 - 4x$

And we want to find:

$\displaystyle f(2b^2)$

Substitute:

$\displaystyle f(2b^2) =(2b^2)^2 -4(2b^2)$

And evaluate:

$\displaystyle \begin{aligned} f(2b^2) &=(2b^2)^2 -4(2b^2) \\ &=(4b^4) +(-8b^2) \\ &= 4b^4 - 8b^2 \end{aligned}$

In conclusion, our answer is A.
