Answer:
{2, 4, 6}
Step-by-step explanation:
the domain is the interval or set of valid x (input) values.
the range is the interval or set of valid y (result) values.
just use the x values in the functional definition and collect the results. these are the range.
x = -1
y = 2×-1 + 4 = 2
x = 0
y = 2×0 + 4 = 4
x = 1
y = 2×1 + 4 = 6
Step-by-step explanation:
seems to be multiplication, because the differences between the numbers change.
so, let's find the factor.
2 × f = 5
f = 5/2
5 × f = 5 × 5/2 = 25/2
ok, the factor 5/2 is confirmed.
a1 = 2
a2 = a1 × 5/2 = 2 × 5/2 = 10/2 = 5
a3 = a2 × 5/2 = a1 × 5/2 × 5/2 = 2 × 5/2 × 5/2 = 25/2
an = an-1 × 5/2 = a1 × (5/2)^(n-1) = 2 × (5/2)^(n-1)
a9 = 2 × (5/2)⁸ = 2 × 390,625/256 =
= 390,625/128 = 3,051.7578125
Exercise 1:
The exponents are wrong: when you divide two power, you subtract the exponents:
Exercise 2:
The function represents a growth rate of 300%! 3% is actually written as 0.03, so the correct function is
Exercise 3:
To factor a quadratic equation, we have to find the roots. Once you have the roots 
, you can factor the expression as 
In this case, the solutions are 
, which yields the factorization
Exercise 4:
When you multiply two powers of the same base, you add the exponents:
So, in your case, you have
