A function is odd if:
f ( - x ) = - f ( x )
A ) f ( - x )= 0.8 ( - x ) ^3 = - 0.8 x^3 = - f ( x )
Answer: A ) f ( x ) = 0.8 x^3 is an odd function.
Functions B ) and C ) are even and D) is neither even nor odd.
Answer: D
Step-by-step explanation:
Using the equation y = mx + b.
m represents the slope
b represents where the line crosses the y axis.
We can attempt to set up the equation given in the same way.
x - y = 0
Add y to both sides and the 0 can drop out.
x = y
This is also equal to:
y = x
In this equation the m is equal to 1 and the b is equal to 0.
Taking this into account the answer is D.
Answer:
2
Step-by-step explanation:
-5(3)-4=-19
-2-5(3)= -17
