These are the formulas right?.. I hope so, anyways..
- f(n)= 2^(n-1) -1
- g(n)=3n+6
f(7)=2^{7-1}-1 - f(7)=2^{6}-1 - f(7)=64-1 - f<u>(7) = 63
</u>
g(10)=3\X 10+6 - g(10)=30+6 - g<u>(10) = 36</u>
= <u>f(7)>g(10)</u>
I hope that it helped..
Answer: Choices C and D
Explanation:
Positive values of 'a' will make the parabola open upward.
Think "positive" as in "happy smile" to help remember this. In contrast, if 'a' is negative, then it is angry or sad to make a frown.
Y=3ˣ and y=2x+1
one of them is the grouth of the flies and the other is how many the iguana can eat per week (I'm thinking the y=3ˣ is the population growth)
where x=number of weeks and y=number of flies
so he should graph y=3ˣ and y=2x+1 and see the solution wich will be the inersection point of the 2 equations
to graph y=3ˣ, graph the points (0,0) and (1,3) and (2,9) and (5,243) then connect the points in a curve
to graph y=2x+1, graph the points (0,1) and (2,4) then connect the points with a straight line
where they intersect is the week and number of flies
to graph y=2x+1
