Question

If f(x)= 2x 2 + 3, then f(x - 1)= 2x 2 + 4x + 5.
True or false

Answer 1

assume the 2x 2 = 2x^2 ?

Answer 2

so false?

Answer 3

mlhuyk it would be helpful if you used 2x^2 for 'two x squared'

Answer 4

it is false... f(x) = 2x^2 + 3... f(x-1) = 2(x-1)^2 +3 = 2(x^2 -2x +1) +3= 2x^2 -4x +5...
