F(x)'s domain is the extent of its x-values and the function x^2 + 3 extends to infinity and negative infinity so its domain is all real #s,
f(x)'s range is its y-values and f(x) is only defined for and values above 3, so its range is y>= 3
f(x)^-1 is the function (x-3)^(1/2) which is a square root function and x >= 3 because if x were to be 2 there would be a negative in the square root which means the y-value would be on the imaginary axis.
the range is y>= 0 because the output of the square root function can never be negative in this context as it is not being multiplied by a negative on the front
Answer:
Hi
The answer is C
Step-by-step explanation:
Because it descend means goes down so it's minus and after that it ascends means goes up so it's plus so the answer will be -
26,843-1,284+5832

Answer:
y = 90
Step-by-step explanation:
If y varies jointly as x and z, then;
y = kxz
If y = 18 when x = 2 and z = 3
18 = k(2)(3)
18 = 6k
k = 18/6
k = 3
To get y when x = 5 and z = 6
y = kxz
y = 3(5)(6)
y = 15*6
y = 90
Hence the value of y is 90
