Answer:

f(-4) = 12

Step-by-step explanation:

Hello!

Here f(x) = -8 - 5x.  We want f(-4).

Subst. -4 for x in the above equation.  Then f(-4) = -8 -5(-4) = -8+20 = 12.

Represent the geometric series using the explicit formula. 3, −6, 12, −24, … f(n) = 3 ⋅ (2)(n−1) f(n) = 3 ⋅ (−2)(n−1) f(n) = f(n
mr Goodwill [35]

Answer:

f(n)=(-2)(n-1)

Step-by-step explanation:

Each term of this Geometric Series (3, −6, 12, −24, ...) can also be found through this explicit formula: f(n)=(-2)(n-1) Because the n^{th} term is found by the product of its common ratio "q", times its predecessor n-1. Where n, refers to the order of the term.

So let's test it, suppose we want to find the 4th term. We know the common ratio and the first term. Then we can write f(n) as:

\\f(n)=3(-2)^{n-1}

f(4)=f(3)*-2⇒-24=12*-2⇒-24=-24

The explicit formula is ok.

Let g be the function given by g(x)=-3x^2-2x+3 evaluate g(-2)
sashaice [31]

g(-2) = -3(-2)² - 2(-2) + 3

g(-2) = -12 + 4 + 3 = -5

which digit can replace the? to make this number sentence true 736,554 < 7?6,573 < 736,589 only one answer
mars1129 [50]
You need 3 for ? to make this sentence true, because if you place 3 for ?, 736,554<736,573<736,589 makes sense. If you compare the three numbers, 736,554 is the smallest, then 736,573, and 736,587 is the biggest number.
Hope this answered your question!
