Question 1026319
.
Please help me solve this problem: 

Given the function h(x)=g(x)-f(x) if g(x) passes through the point (2,3) and f(x) passes through the point (2,-8), then, h(x) must pass through the point (2,k). The value of k is? 

Thank you in advance, your help is appreciated.

k = 11.


Because 11 = 3 - (-8).
