Which of the following functions represent exponential growth?

The difference of 2 numbers is 21 and the quotient of the equation is 4 then what are the two numbers?

F(x) = x2 − 9, and g(x) = x − 3 f(x) = x2 − 4x + 3, and g(x) = x − 3 f(x) = x2 + 4x − 5, and g(x) = x − 1 f(x) = x2 − 16, and g(x) = x − 4 h(x) = x + 5 arrowright h(x) = x + 3 arrowright h(x) = x + 4 arrowright h(x) = x − 1 arrowright

Ab based on the given diagram, if m_1 = 60° then m 2 = 30 60 90 180
