Exponential function
laiz [17]
A typical exponential function is y=ab^{x}
when x=3.5, y=16.2
when x=6, y=3936.6
plug these values into the exponential function:
16.2=ab^{3.5}
3936.6=ab^{6}
divide the second equation by the first to eliminate a:
243=b^{(6-3.5)}
log both sides: log243=2.5logb
logb=log243/2.5
use your calculator to find b: b=3.6
plug b=3.6 in the first equation to find a:
16.2=a* (3.6)^{3.5}
a=0.183

please double check my calculation

Answer:

2x^4+4x^2+2

Step-by-step explanation:

f(x) = x^2+1

g(x) = 2x^2

g(f(x))=

Replace x in the function g(x) with the function f(x)

         =2( x^2+1)^2

         = 2( x^2 +2x^2 +1)

         = 2x^4+4x^2+2
