Question

what is the range?
w(x) = 3(2)^x

Answer 1

$w(x) = 3 \times (2)^x$

2^x is always greater than 0.

So 3×2^x will be also greater than 0.

Range is (0, infinity)

Answer 2

The range of f (x) = x 2 + 5 is given by the interval: [5 , +∞) ... f(x)< -3 e 5 + 2 which means that the range of function f is given by the ...
