(b) recall that for d c x, the image of d under f is the set f (d) = {f(x) e y |x € x}. let a, b c x prove that f(an b) c f(a) n f(b). find an example of a function f and sets a and b such that f(an b) but f(a)n f(b)ø

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.

what’s the question?

486in is correct

step-by-step explanation:

m∠abd = m∠dbc

step-by-step explanation:

given : ab bisects ∠dbc

as we know that bisection means ab divides   ∠dbc   in two equal angles named as   ∠dba and   ∠abc

so, m∠abd = m∠dbc  

because ab bisects ∠dbc.

hence , the first statement m∠abd = m∠dbc is true.
