Use mental math strategies to solve the problem.there are 35more musicians in the string section of a city symphony orchestra than in its brass section.there r 29 musician in the brass section . how many musicians are in the string and brass sections of the symphony orchestra?

This represent an exponential function, because his savings increase by a constant factor of 2.

It is given that,

Luis has saved $3 and he doubles the amount each week.

So, the amount saved in the next week = 3×2 = 6

This gives the amount saved in the third week = 6×2 = 12

So, we get the sequence 3,6,12...

It can be written as, 3×2⁰, 3×2¹, 3×2², 3×2³,.....

So, the sequence in the exponential form , where 'n' is a natural number.

Also, 3,6,12...

The numbers are increasing by the factor =

Hence, we get,

This represent an exponential function, because his savings increase by a constant factor of 2.
