Answer:
range of the given function in Interval notation is [-1, 3]
Step-by-step explanation:
i) given function is y = 1 + 2sin(x - 11)
ii) maximum of sin function is 1
iii) therefore maximum of given function = 1 + (2 1) = 3
iv) minimum of sin function is -1
v) therefore maximum of given function = 1 + (2 -1) = -1
vi) therefore the range of the given function in Interval notation is [-1,3]
Answer:
17
Step-by-step explanation:
To evaluate the expression substitute x = - 1 and y = 3 into it
3(- 3)² - 2(- 1) - 12
= 3 × 9 + 2 - 12 = 27 + 2 - 12 = 29 - 12 = 17
