Find the vaule of f(5) for the function. f(x)= -4(x+4)

-36

Step-by-step explanation:

f(5)= -4 (5+4).

= -4×9

=-36

-36

Step-by-step explanation:

Put 5 in x

we have:

f(5) = -4(5+4)

      = -4 x 9

      = -36

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
