Question

The graph of the logarithmic function y = loga(x) always passes through what point?
Options Are:
1.(0,1)
2.(a,0)
3.(0,a)
4.(1,0)

Im Bamboozled! please help q_q

Answer 1

look at the graph of log(x)

Answer 2

they dont give you the value of a do they?

Answer 3

nope

Answer 4

log_a(x) = y
is the same as
x = a^y

Answer 5

what happens when you set y = 0?

Answer 6

then a is 1?

Answer 7

if you set y = 0, x = 1

because remember

when you take anything to the exponent 0 it always equals one

an exception to this is 0^0 which is undefined

Answer 8

this is a fundamental rule commit it to memory

Answer 9

you should be able to tell me the point now :) since I pretty much gave you the answer

Answer 10

wow i get it! thanks alot Mr!

Answer 11

Another thing you should commit to memory is that

x > 0

or in english x is always greater than 0, if you are working with real numbers you cannot put a negative number in a logarithm

Answer 12

You can sub any number into y and you will never get out a negative x value
10^y = x
