Which equation is an exponential equation?(1 point)

Question

Responses

y=x−−√
y is equal to square root of x

y=515(7)x
y is equal to 515 times 7 to the x th power

y=−23x+7
y is equal to negative 2 thirds x plus 7

y=5x2

Answer 1

The equation that is an exponential equation from the options provided is:

y = 515(7)^x

In this equation, \(7\) is raised to the power of \(x\), which is the defining characteristic of an exponential function. The other equations do not have this form.
