Answer:
the graph of f(x) will be reflected over x axis, moved 8 units to the right and shifted 20 units up to get g(x)
Step-by-step explanation:
The function written in vertex form is
The parent function is f(x)=x^2
Now we compare parent function f(x) and g(x)
In g(x), negative sign at first
f(x) ----> -f(x) , the graph is reflected across x axis
f(x)-----> f(x-h), the graph will be transformed h units to right
f(x)----> f(x) +k , the graph will be transformed k units up
, the graph of f(x) will be reflected over x axis, moved 8 units to the right and shifted 20 units up to get g(x)

The formula for E(x) would be SUM[ X(n)P(n)] from n = 1 to n = infinity until we get the prime number
In the given problem, a 10-sided die with 1-10 numbers is rolled until we get a prime number
Prime numbers between 1-10 = 2,3,5,7 (4 prime numbers)
Non - prime numbers = 1,4,6,8,9,10( 6 non-prime number)
Let X be the number of times the die is rolled
The probability of getting a prime =
Now, the value of
E(X)=∑x.P(x) [ x-> {1, infinity}]
= P(1)X(1) +P(2)X(2)+P(3)X(3)+P(4)X(4)........+ P(n)X(n)
= 1. + 2.

Hence, this is the value of E(x)
