1.What element in the domain has image 7 under the function f(x) = 7x - 8?
2.If f(x) = 7x - 5, what is the value of f(5) and (f8)?
3.If f(x) = x^2, find the value of [f(a+h)-f(a)]/h.
4.If f(x+3 ) = f(x) + f(3), show that i) f(0) = 0 ii) f(-3) = -f(3)
5.If f(4x) = f(4) + f(x), show that i) f(4) = 0 ii) f(16) = 0

answer: a

step-by-step explanation: the answer is a due to the rule of symmetry; that a line of symmetry must divide a figure into 2 pieces that are the exact same, only reflected over a line of symmetry. b and c do not have lines of symmetry and would not divide the figure evenly, thus making the answer a.

answer: the answer for that is 22/3
