If ƒ(-7) = - 3 and ƒ'(x) ≤\le≤ 2, for all x ∈\in∈ (-7,0), then for all such functions ƒ, ƒ(-1) + ƒ(0) lies in the interval:A[−6,20]\left[ { - 6,20} \right][−6,20]B(−∞,20]\left( { - \infty ,\left. {20} \right]} \right.(−∞,20]C[−3,11]\left[ { - 3,11} \right][−3,11]D(−∞,11]\left( { - \infty ,\left. {11} \right]} \right.(−∞,11]Check answerSkip
