Answer:
b and c, b and c are same
Step-by-step explanation:
Only a and d can be evaluated using simple substitution.
For a, integral of the square root of (x-1)dx i.e
let y = x-1
dy = dx
It becomes integral square root of ydy, ∫√ydy
which is can easily be evaluated and y is substituted back.
For d, integral of x times the square root of the quantity x squared minus 1
let y= x squared minus 1
then dy = 2xdx
dx = dy/2x
It becomes integral x times square root of y dy/2x
∫x√ydy/2x=∫√ydy/2=1/2∫√ydy which can easily be evaluated and y is substituted back
Y = (5.2)^x is exponential growth.
The exponential equation is y = a * b^x
If b > 1 then the function is exponential growth.
If 0 < b < 1 then the function is exponential decay.

Answer:
Step-by-step explanation:
g(2) = 3(2) - 3 = 6 - 3 = 3
h(3) = 3^2 - 4(3) = 9 - 12 = -3
A is the answer
