The answer is C. g(-13) = 20.

The best way to approach this problem is by process of elimination. You can immediately cross out option A, since it explicitly states that g(0) = -2. It cannot be B because although the x-value falls under the domain, the function value, -11, falls outside of the range value. It cannot be D either since the x-value, 7, falls outside of the domain. The final choice, C, is correct because both x and g(x) fall under their restraints.

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval
