Given g(x) = (1/2) ^2x 

 

g(-1) = I found : (1/2) ^2*(-1) = -0.25

 

2. Given f(x) = e^3x, evaluate the following. Round your answer to the nearest ten-thousandth. 

 

A. F(-2) 

 

B. f( - 4/5) 

 

C. f(2) 

 

Please what I am supposed to do with the E ??? 

 

 

Best, 

and Thank you ! :)

A . -40.1711 

 

B . 11.0230

Right ?

Assuming that the "x" is part of the exponent, we have :

 

(A)  f(-2) = e^(3 * -2)  = e^(-6) = 0.0024787521766664

 

(B) f( -4/5) = f(-.8)  = e^(3 * -.8)  = e^(-2.4) = 0.0907179532894125

 

(C) f(2)  = e^(3 * 2) = e^6  = 403.4287934927351226

 

 

 

cool cool cool
