Which is a zero of the function f(x) = 2x - 10?

[tex]f(x)=2x-10\\\\a\ zero\ if\ 2x-10=0\\\\2x=10\ \ \ /:2\\\\x=5\\\\Answer:The\ zero\ is\ x=5.[/tex]

Watch carefully:A 'zero' of the function is a value of 'x' that makes the function zero.2x - 10 = 0Add 10 to each side:2x = 10Divide each side by 2 :x = 5f(5) = 0
