Given y=log3(x+4) what is the domain
Luden [163]
As you know, the domain is the values "x" can safely take on.

well, for a logarithmic expression, it can never have an expression of 0, namely in this case, x + 4 must never be 0, since such a logarithm doesn't exist.

now, x + 4 = 0 ---> x = -4.

thus if "x" ever becomes -4, we'd end up with log₃(-4+4), or log₃(0), which is a no dice.

so the domain is all values except -4.

Find the value of x. help with geometry pls
Ivan

Answer:

Find the value of x:-

To find Y, use Pythagorean theorem:- c^{2} =a^{2} +b^{2}

(2.1)^{2} =y^{2} +(1.4)^{2}

2.1^{2}=4.41

1.4^{2} =1.96

4.41=y^{2} +1.96

subtract 1.96 from both sides

2.45=y^{2}

y=1.5652

Now, to find x:-

x=y+y

= 1.5632+1.5652

x=3.1 \: ft
