= 10.5 - 3n

Step-by-step explanation:

The explicit rule for an arithmetic sequence is

= a₁ + (n - 1)d

where a₁ is the first term and d the common difference

A recursive formula has the form

= + d ( where d is the common difference )

Given

= - 3 ⇒ d = - 3

Thus explicit rule with a₁ = 7.5 and d = - 3

= 7.5 - 3(n - 1) = 7.5 - 3n + 3 = 10.5 - 3n

could u provide us some answer choices or hmm idk maybe a table for us to anser with ? ?

hello,

as we don't know if g(x) is continue,

answer b

f(x)=2x²-8x+1=2(x²-4x+4)+1-8=2(x-2)²-7

vertex is (2,-7) ( a minimum since coefficient of x² is > 0)
