B. g(x) = 42
A flip over the x-axis means you flip the sign. A stretch means you multiply the factor of stretch to the coefficient.

I need help with this if anyone can help

Fiesta28 [93]

Answer: $\Large\boxed{Fourth~Choice.~f(x)=2-i}$

Concept:

Here, we need to know the power of imaginary numbers

i = √(-1)

i² = -1

i³ = -i

i⁴ = 1

Solve:

<u>Given function expression</u>

$f(x)=x^3-2x^2$

<u>Given the requirement of the question</u>

To find the expression for f(i)

<u>Substitute values into the expression</u>

$f(x)=(i)^3-2(i)^2$

<u>Simplify the exponents</u>

$f(x)=(-i)-2(-1)$

<u>Expand the parenthesis</u>

$f(x)=-i-(-2)$

$\Large\boxed{f(x)=2-i}$

Hope this helps!! :)

How do I figure this out??

The function is divided by 12, you would find it out by dividing 120 by 10 and getting 12, if you wanted to check your answer, you would do 84 divided by 7 which is 12. the answer to 12 is 1 and 24 is 2. hope this helped :))
