Hi there!

$\large\boxed{\text{ B. 2}}$

f(x) = 2x + 6

Differentiating 2x = 2 (Power rule, dy/dx xⁿ = nxⁿ⁻¹)

Differentiating a constant always equals 0.

Thus:

f'(x) = 2

Consider the recursive formula an = (2 + an-1) / 2

wel

Answer: The correct option is B. The third term is 4.

Explanation:

The given recursive formula is,

$a_n=\frac{2+a_{n-1}}{2}$

It is given that the first term is 10. So,

$a_1=10$

To find third term, first we have to find the second term.

$a_2=\frac{2+a_{2-1}}{2}$

$a_2=\frac{2+a_{1}}{2}$

$a_2=\frac{2+10}{2}$

$a_2=\frac{12}{2}$

$a_2=6$

Therefore the second term is 6.

$a_3=\frac{2+a_{3-1}}{2}$

$a_3=\frac{2+a_{2}}{2}$

$a_3=\frac{2+6}{2}$

$a_3=\frac{8}{2}$

$a_3=4$

Therefore, the correct option is B. The third term is 4.

-12 + (-5)= someone plz help

marishachu [46]

I think it is -7 because the + and the - cancel each other out and you subtract 12 and 5 and keep the sign of the bigger number which is 12 so -7. I’m not 100% sure but I think it’s right.

How do I justify if these functions are inverses of each other ... F(x)=x^3 +4 & g(x)=3(radical sign) -4

lapo4ka [179]

You plug them into each other for x like so:
(3(radical sign)-4)^3+4
-4+4
You're left with x
Then do the same for the other one
3(radical sign)(x^3+4)-4
X+4-4
Left with x again there fore it is an inverse
