The answer is 8. 2n means 2*n, which is 2*4.
Step-by-step explanation
Answer:
x^2−6x+9
Step-by-step explanation:
To write a polynomial in standard form, simplify and then arrange the terms in descending order.
ax^2 + bx + c
Rewrite (x - 3)^2 as (x -3) (x-3).
(x - 3) (x - 3)
expand (x - 3 ) (x - 3) using the FOIL method
Apply the Distributive property
x (x - 3) - 3 (x - 3)
again
x * x + x * -3 - 3 (x- 3)
and again
x * x + x * -3 - 3x - 3 * -3
then simplify and combine like terms
- Multiply x by x
x^2 + x * - 3 - 3x -3 * -3
- Move -3 to the left of x
x^2 - 3 * x - 3x - 3 * -3
Multiply -3 by -3
x^2 - 3x - 3x + 9
Subtract 3x by -3x
x^2 - 6x + 9
Hope that helps!
Answer:
f(x)= 2ˣ
We have to find x when f(x) is 8
8=2ˣ
we can write 8 in exponential form as 2³
2³=2ˣ
here base is same (2) on both left and right side
comparing the powers we get
x=3
