Question

Which is not a correct description of the graph below? nh -2TT -TK 2TT The graph of y = cos & shifted to the left by 34 units. Зл 2 The graph of y = sin e shifted to the left by n units. O y = sin(0 + 21) = O y = cos(0+ y = 3 Зл 2

Answer 1

Verify each statement

N 1 -----> is true

because

y=cosx , shifted to the left by 3pi/2 is y=cos(x+3pi/2)

N 2 ----> is false

N 3 -----> is true

N4 ----> is true

therefore

the answer is option N 2
