Solve the problem. determine which of the following sets is a subspace of pn for an appropriate value of n. a: all polynomials of the form p(t) = a + bt2, where a and b are in ℛ b: all polynomials of degree exactly 4, with real coefficients c: all polynomials of degree at most 4, with positive coefficients

Only and form subspaces of and , respectively.

does not form a subspace because it does not contain the zero vector.

the answers are in the images, i received 100% on this assignment. hope this !

graph b

step-by-step explanation:

one solution- graph a (clear intercepting point.)

no solution- graph b (they're parallel, there will never be a point of interception.)

infinite solutions- graph c (all points intercept.)
