The domain of the function 3x² + 6x – 8 is a real number and the range of the function 3x² + 6x – 8 will be (-11, ∞).
<h3>What are domain and range?</h3>
The domain means all the possible values of the x and the range means all the possible values of the y.
The function is given below.
f(x) = 3x² + 6x – 8
The range of the function will be
f(x) = 3x² + 6x – 8
f(x) = 3x² + 6x + 3 – 11
f(x) = 3(x² + 2x + 1) – 11
f(x) = 3(x + 1)² – 11
Then the range of the function will be from -11 to infinity.

Answer:81
Step-by-step explanation:
He spends $625. 25 percent equals 1/4. If you divide 2500 divided by 4 is 625.
For the question 2
the square root of a is a^(1/2)
so you can multiply a^2 and a^(1/2)
to get a^2.5
(a^3)^2 is equal to a^6
Divide a^2.5by a^6
The answer is a^(-3.5)
or 1/a^(3.5)
