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 set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.

cpctc makes it so that corresponding parts of the triangle you proved to be equal are equal, the other options aren't part of the part of the triangles you proved to be equal.
