If f(x)=2(3^x)+1, what is the value of f(2)

19

Step-by-step explanation:

f(x)=2(3^x)+1,

Let x=2

f(2)=2(3^2)+1

Exponents first

     =2 (9) +1

Then multiply

     =18+1

     =19

19

Step-by-step explanation:

f(2) = 2(3²) + 1

= 2(9) + 1

= 18 + 1

= 19

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.

d. corresponding side lengths in similar triangles are proportional in length.
