What is the domain of the function y = √x + 4 ?

Hello from MrBillDoesMath!

Answer:

Domain: x >=0 for both cases

Discussion:

Assuming we are dealing with real valued functions, the domain of

y = x^(1/2) +4

is the set of all "x" such that x>= 0 (so we are taking the square root of a positive, or zero, real number)

The domain of x^(1/2) +6 -7 is the same as for the last function and for the same reason.

Thank you,

Algebraically solve the system of equations shown below. Note that you can use either factoring or the quadratic formula to find

ivann1987 [24]

$6x^2+19x-15=-12x+15\\
6x^2+31x-30=0\\
6x^2+36x-5x-30=0\\
6x(x+6)-5(x+6)=0\\
(6x-5)(x+6)=0\\
x=\frac{5}{6} \vee x=-6\\\\
y=-12\cdot\frac{5}{6} +15\vee y=-12\cdot(-6)+15\\
y=-10 +15\vee y=72+15\\
y=5 \vee y=87\\\\
x=\frac{5}{6} \wedge y=5\\
x=-6 \wedge y=87$
