1. The problem statement, all variables and given/known data Express the following signal in terms of ramp, exponential, and parabolic functions, where t should be consistently shifted 2. Relevant equations signal simplification techniques, not known to me 3. The attempt at a solution It seems you can express this in terms of step functions too, but not sure. x(t) = -4(t + 4) x(t) = -4r(t - 1) I know you were supposed to have a ramp function here though.
