Well what i think you're asking here...I apologie if I'm wrong but what I did was
f(-1) = 4 * 7^t = 4/7
and
f(2) = 4 * 7^t = 196.
Is this what you wanted if not I can...try another way.
Answer:
1) C
2) B
Step-by-step explanation:
1) If a point lies ON the yz-plane, no matter what its coordinates are, one thing is for sure that its x-coordinate will always be zero! (this is helpful for visualization).
This information can guides us about which coordinate is responsible for how close or far we are to yz-plane!
The closest point to yz-plane would be the point the smallest value of x-coordinate. regardless of the the side.
here, among A,B, and C. C has the smallest x-coordinate, hence C is closest to the yz-plane.
2) If a point lies on xz plane, no matter what its coordinates are, its y-coordinate will always be zero.
Hence, among A,B, and C. A is the coordinate with y-coordinate as 0. Hence, B lies on the xz-plane.
Answer:
38w (miles)
Step-by-step explanation:
38 miles per week
w weeks
-> 38w (miles)
Option a) -10
put $x=-1$
$f(-1)=-|(-1)^2-5(-1)+4|$
$\implies f(-1)=-|1+5+4|=-|10|=10$
