Step-by-step explanation:
the domain: no real numbers so its negative infinity, positive infinity
Answer:
$19.6
Step-by-step explanation:
He bought 6 video games and 1 dvd
We know that each video game costs $2.7 and each dvd costs 3.4
To get the sum = v x 6 + d x 1
= 2.7 x 6 + 3.4 x 1
= 16.2 + 3.4
= $19.6
The given function is
f(x)= 0.2 x²
Since f(x) will be defined for all real values of x.
So, Domain of f(x) will be ( x| x is a real number.)→This is set builder notation.
Finding the inverse of f(x):
y = 0.2 x²
→ x²= 5 y
→x =
→ → Inverse of f(x)
Replacing x by y and y by x,we get inverse of the given function
y =
→ →Domain x ≥ 0, x∈[0,∞]
Graph of function and its inverse are shown below.
