Question

Fiona has proved that a function, f(x), is an arithmetic sequence. How did she prove that?

Answer 1

f'(x) = constant

Answer 2

a constant ratio?

Answer 3

arithmetic sequence has form, if the first term is a
{a,a+k,a+2k,a+3k,...}

Answer 4

not a constant ratio between them, a constant difference

Answer 5

oh i see now thank you

Answer 6

linear change, f(x)= degree 1 polynomial
therefore f'(x) = constant
