F(n)=5.(-2)n-1<br>Complete the recursive formula of f(n).

Alex73 [517]

Answer:

a(n) = $(-2)(a_{n-1})$

$a_{1}=5$

Step-by-step explanation:

The given expression is in the form of the explicit formula of a geometric sequence.

f(n) = $a(r)^{n-1}$

Where 'a' = First term of the sequence

r = common ratio

Recursive formula of a geometric sequence is,

a(n) = $(a_{n-1}).(r)^{n-1}$

a(n) = $(-2)(a_{n-1})$

Where, $a_{1}=5$

So the recursive formula will be a(n) = $(-2)(a_{n-1})$

What statements about the graphs of these two functions are true?

tamaranim1 [39]

Answer:

B)Only one graph intersects the y-axis above y=0

Step-by-step explanation:

Both functions are in y=mx+b. The y-intercept is b.

f(x) has the y-intercept 3. It intersects above y=0.

g(x) has the y-intercept -4. It intersects below y=0.

This means B is correct.
