Answer:
g(4) = 12
Step-by-step explanation:
We need to find the value the function g(x) when x = 4, that is;
g(4)
In the first definition of the function, the value of x is strictly less than 4. Consequently, we shall use the second definition of the function to evaluate g(4)
In the second definition, g(x) is given as;
Q(x) = 0.5x + 10
plug in x = 4 and simplify;
Q(4) = 0.5(4) + 10
Q(4) = 12

Answer:
8,840
Step-by-step explanation:
Multiply 4420 by 200% to get the answer 8840. You can also multiply 4420 by 2 to get the same answer as you would multiplying by 200%.
Answer:
y = 2( x-3)^2 +5
Step-by-step explanation:
The vertex form of a parabolic functions is
y = a( x-h)^2 +k
where (h,k) is the vertex
y = a( x-3)^2 +5
Substituting the point into the equation
13 = a( 1-3)^2 +5
13 = a*( -2)^2 +5
13 = 4a +5
Subtract 5
8 = 4a
Divide by 4
8/4 =a
2=a
y = 2( x-3)^2 +5
