Question

The x-intercept of the graph f(x)=log15 X is (1,0)

Answer 1

true or false

Answer 2

true

Answer 3

x-intercept would be let f(x) = 0 then solve for x

\[0 = \log_{15} (x)\]
change to exponential form
\[15^0 = x\]
\[\implies 1 = x\]
therefore x = 1; y = 0

so the coordinate would be (1,0)

Answer 4

Find the zero(s) of the function f(x) = 6x.
Hint: The zeros are all the values of x when f(x) = 0

Answer 5

so let f(x) = 0

0 = 6x

solve for x

Answer 6

so is it 6

Answer 7

no...what will you multiply 6 so the product is 0

Answer 8

0

Answer 9

right. therefore x = 0 is the zero

Answer 10

ok

Answer 11

what would this graph look like y = log3x
