Answer:
= -x^2 -x +6
D: all real values
Step-by-step explanation:
f(x) = 4-x^2
g(x) = 2-x
f+g = 4-x^2+ 2-x
Combine like terms
= -x^2 -x +4+2
= -x^2 -x +6
The domain is what values can x take
D: all real values
Yes, because the x doesn’t repeat. The y is not as important so it’s fine if it repeats numbers.
Tree A grew slower.
4.15 is less than 4.2 and Tree A is growing at the “lesser” rate, making it the slower growing tree.
C is the only one that is perpendicular.
The quickest way I can explain it is that the y-axis runs up and down, making the slope undefined. Something perpendicular to an undefined slope is a 0-slope. The only equation of the choices that has a 0-slope is C. Comment if you want a more detailed answer.
