Graph the first six terms of a sequence where a1 = 3 and d = −10.

Aleks [24]

Answer:

Step-by-step explanation:

nth term = (n-1)th term + common difference

d = -10

a₁ = 3

a₂ = a₁ + d = 3 + (-10) = -7

a₃ = a₂ + d = -7 + (-10) = -17

a₄ = a₃ + d = -17 + (-10) = -27

a₅ =a₄ + d = -27 + (-10) = -37

a₆ = a₅ + d = -37 + (-10) = -47

First six terms: 3 , -7 , -17, -27, -37 , -47

If the zeros of f(x) are x=-1 and x=2, then the zeros of f(x/2) are

RSB [31]

Answer:

E (-2, 4).

Step-by-step explanation:

(x/2 + 1)(x/2 - 2) = 0

x/2 = -1, x/2 = 2

x = -2, 4.

The roots will be 2 times the roots of f(x).

(7.06) what function is represented below

wel

I can eyeball points (1/2, 8), (1,4), (2,1), (3,1/4)

The pattern is each increment of 1/2 in x divides by two.

$f(x) = (\frac k 2)^{2x} = \frac{k}{4^x}$

Any of the points give k=16

$f(x) = 16( 4 ^{-x} ) = 4^{2-x}$

Check: x=1/2 4^(3/2)=2^2=8 good

x=1 4^(2-1)=4 good

x=2 4^(2-2)=1 good

x=3 4^(2-3)=1/4 good
