How do you find the y intercept of an exponential function #q(x) = -7^(x-4) -1#?
The y intercept of ANY function is found by setting
For this function is the y intercept is
The y intercept of ANY two variable function is found by setting
We have the function
So we set x=0
flipping the negative exponent upside down we have
Now we just play with the fractions to get the correct answer.
