Example Question #41 : Exponents
Find the -intercept(s) of
.
This function does not cross the -axis.
To find the -intercept, set
in the equation and solve.
Example Question #1 : Graphing Exponential Functions
Find the -intercept(s) of
.
and
To find the -intercept(s) of
, set the
value equal to zero and solve.
Example Question #32 : Solving And Graphing Exponential Equations
Find the -intercept(s) of
.
and
and
and
To find the -intercept(s) of
, we need to set the numerator equal to zero and solve.
First, notice that can be factored into
. Now set that equal to zero:
.
Since we have two sets in parentheses, there are two separate values that can cause our equation to equal zero: one where
and one where
.
Solve for each value:
and
.
Therefore there are two -interecpts:
and
.
Example Question #1 : Graphing Exponential Functions
Find the -intercept(s) of
.
The function does not cross the -axis.
or
To find the -intercept(s) of
, we need to set the numerator equal to zero.
That means .
The best way to solve for a funky equation like this is to graph it in your calculator and calculate the roots. The result is .
