Answer:
a = 
Step-by-step explanation:
Given
ai + bj and 5i - 2j are perpendicular and b = 3, that is
ai + 3j and 5i - 2j are perpendicular, then
The scalar product = 0 , that is
5a - 6 = 0 ( add 6 to both sides )
5a = 6 ( divide both sides by 5 )
a = 
x = 0
f(x) = -9(3)^0
Anything to the power of 0 is 1,
f(x) = -9(1)
f(x) = -9
The answer is -9
