Question

ITF problem pls help​

Answer 1

since it is even function therefore f(x)= f(-x) hencef(-3) = 2 f(-1) = -3f(7/8) is between -2 to -3 and by considering the gif it will be equal to = -2

f(0) =0

arc cos f(-2 )= π/2

f(-7) = 1

f(20) = 3

now put the values that will give the eqn. 2-3-2+0+π/2 + 1 + 3

2-3-2+0+π/2 + 1 + 3 => π+2/2If it is correct then no problem but if not than change the value of of gif function= -3

hope it will help you
