Answer: The answer is (b) (2, ∞)
Step-by-step explanation: We are given a function f(x) in the figure and we are to select out of the given options that accurately shows the range of the function defined.
![\textup{For }x < 0, \textup{we have}~f(x)=3.](https://tex.z-dn.net/?f=%5Ctextup%7BFor%20%7Dx%20%3C%200%2C%20%5Ctextup%7Bwe%20have%7D~f%28x%29%3D3.)
![\textup{For }0\leq x](https://tex.z-dn.net/?f=%5Ctextup%7BFor%20%7D0%5Cleq%20x%3C2%2C%5Ctextup%7B%20we%20have%20%7Df%28x%29%3Dx%5E2%2B2%5Cgeq%202.)
![\textup{For }x\geq 2,\textup{ we have }f(x)=\dfrac{1}{2}x+5\geq 5.](https://tex.z-dn.net/?f=%5Ctextup%7BFor%20%7Dx%5Cgeq%202%2C%5Ctextup%7B%20we%20have%20%7Df%28x%29%3D%5Cdfrac%7B1%7D%7B2%7Dx%2B5%5Cgeq%205.)
Therefore, the range of the function f(x) will be greater then or equal to 2. So, the range will be [2, ∞).
Thus, the correct option is (b) (2, ∞).
Answer:
6x3
Step-by-step explanation:
sorry if wrong
Answer:
Rate = (4C)cars/3(H)hrs
Step-by-step explanation:
The expression of the above formula for C fraction of 4 cars and H fraction of 3 hours will be 4(C)/3(H) since he can tune 4 cars every 3 hours
So, the coefficients are 24, -3, and 7. The letters next to the coefficients are called "variables".
