Let the smaller number be n:
Therefore 1/2 * n(n+1) = 105
n^2 + n = 210
n^2 + n - 210 =0
Use your preferred method to solve the quadratic, I'll factorise this since this is easy to factorise.
Two numbers':
product gives -210
summation gives 1
Therefore (n+15)(n-14)=0
So the smaller number n is either -15 or 14.

Answer:
answer is (a)
Step-by-step explanation:
first thing we should find the equation which is f(X)=a*b^x
so the always will be the y intercept no matter what
now time to find b if graph that is shown start from 1 until the end of line which is in the graph so you will find it 8 now divide 8 by 4 so 8/4=2
so final equation will be f(x)=2*(4)
i hope i helped out
