Answer:
Step-by-step explanation:
in the expression f(x), x is just a place holder. It can be replaced with any value you choose.
f(t-4) = 7(t-4) - (t-4)^2
f(p+4) = 7(p+4) - (p+4)^2
f(a+h)-f(a) = 7(a+h)^2 - (a+h)^2 - (7a-a^2)
f(t-1)+c = 7(t-1) - (t-1)^2 + c
f(a)+8 = 7a - a^2 + 8
you can simplify these some
