Given the two functions below with their provided domain, determine which function to substitute into and find the value of f(-3).

Provide your numeric answer as well as a detailed response on how you determined your answer and why you believe it is correct.

f ( x ) = 2 x − 5 if x ≤ − 3
f ( x ) = − 3 x + 4 i f x > − 3

Sketch the vector field vector f( vector r ) = 8vector r in the xy-plane. select all that apply. the length of each vector is 8. the lengths of the vectors decrease as you move away from the origin. all the vectors point away from the origin. all the vectors point in the same direction. all the vectors point towards the origin. the lengths of the vectors increase as you move away from the origin.
