which is an exponential equation
y=x^2
y=5^x
y=2x-3
y=1/x
Out of the equations you provided, the exponential equation is:
y = 5^x
To identify an exponential equation, look for the variable being raised to a power or exponent. In this equation, the variable 'x' is raised to the exponent of 5, making it an exponential equation.
To solve this equation, you can use logarithms. Taking the logarithm (base 5) of both sides, we get:
logâ‚…(y) = x
Now, if you have a value for 'y', you can substitute it into the equation to solve for 'x'.
If you're looking for general information on exponential equations, you can study the properties and behaviors of exponential functions, such as exponential growth and decay, by exploring the graph and observing the pattern formed by changing values of the variable 'x'.
