Define Max {a, B} = {B, AB}, then the range of F (x) = max {2 ^ x, 2 ^ - x} is?

Define Max {a, B} = {B, AB}, then the range of F (x) = max {2 ^ x, 2 ^ - x} is?

Max {2 ^ x, 2 ^ - x} is equivalent to
{2^-x,2^x2^-x}
Then, it can be solved according to the priority of operators
Range [1, + ∞)
If you fill in the blanks or choose questions like that, draw a sketch and you'll know
Maybe the image of y = 2 ^ x can be drawn,
The images of y = 2 ^ - X and y = 2 ^ X are symmetrical about the y-axis. The curves on both sides of the y-axis take the upper part, that is, the image of y = f (x)
