Move all terms to the left side and set equal to zero. Then set each factor equal to zero.<span>x=0,−1,<span>1</span></span>

Answer

8 minutes for 2 laps,

So 8x3=24,

So 2x3=6.

You can get around the track 6 times in 24 minutes.

<h2>Exponential Functions</h2>

Exponential functions are typically organized in this format:

$f(x) = a*c^x$

To find the equation given the graph of an exponential function:

Identify the horizontal asymptote
⇒ <em>asymptote</em> - a line towards which a graph appears to travel but never meets
⇒ If the horizontal asymptote is not equal to 0, we add this at the end of the function equation.
Identify the y-intercept
⇒ This is our <em>a</em> value.
Identify a point on the graph and solve for <em>c</em>

<em />

<h2>Solving the Question</h2>

Identify the horizontal asymptote

In this question, it appears to be x = 0.

Identify the y-intercept

The y-intercept is the value of <em>y</em> at which the graph appears to cross the y-axis. In this graph, it appears to be 100. This is our <em>a</em> value. Plug this into $f(x) = a*c^x$ :

$f(x) = 100*c^x$

Solve for <em>c</em>

We can use any point that falls on the graph for this step. For instance, (1,50) appears to be a valid point. Plug this into our equation and solve for <em>c</em>:

$f(x) = 100*c^x\\50 = 100*c^1\\50 = 100*c\\\\c=\dfrac{1}{2}$
