If f(x) = 7x - 5, what is the value of f(5) and (f8)?
If f(x) = x^2, find the value of [f(a+h)-f(a)]/h.
If f(x+3 ) = f(x) + f(3), show that i) f(0) = 0 ii) f(-3) = -f(3)
If f(4x) = f(4) + f(x), show that i) f(4) = 0 ii) f(16) = 0

answer: sine

step-by-step explanation:

answer is b

step-by-step explanation:

twenty-six miles over two gallons because the proportion for the original 13 miles to one gallon would be written 13/1 and, doing the same thing to the top and bottom, i multiplied by 2 and got 26/2
