The y intercept of ANY function is found by setting x=0.
For this function is the y intercept is
q(0)=−174−1=−24022401=1.00041649313

Explanation:

The y intercept of ANY two variable function is found by setting x=0.

We have the function
q(x)=−7x−4−1
So we set x=0
yint=q(0)=−70−4−1
=−7−4−1
flipping the negative exponent upside down we have
=−174−1
Now we just play with the fractions to get the correct answer.
−12401−1=−12401−24012401=−24022401=1.00041649313
