Hi,
I've been having problems with this question on functions, and am hoping someone can help me to understand how to go about it.
Let H be the function given by H(t)= -3. Evaluate H(x-3h) and H(x)-H(x-3).
Thanks,
Maddi
Since $\displaystyle H(t)=-3$ and the function does not depend on the variable, what do you think $\displaystyle H(x-3h)$ will equal? If you can figure this out, then $\displaystyle H(x)-H(x-3)$ should be a cinch to figure out.
Post back if you have any additional questions!
