Answer:
Domain: All real numbers
Domain: x≠2
Step-by-step explanation:
The given functions are
and
This implies that:
We expand to get:
We expand to get:
We group like terms to get:
This is a polynomial function, the domain is all real.
Also;
Factor to get:
Cancel common factors:
The domain is all real numbers, except numbers that will make the denominator zero.
Answer:
C
Step-by-step explanation:
The exponential function has standard form
y = a
Use the 2 given points to find a and b
Using (3, 182.25) , then
182.25 = a b³ → (1)
Using (2, 202.5) , then
202.5 = ab² → (2)
Divide (1) by (2)
=
b = 0.9
Substitute b = 0.9 into (1) and solve for a
182.25 = a (0.9)³ ( divide both sides by (0.9)³
a = = 250
Thus
f(x) = 250 × ← third option
