What statement correctly describes the key features of the graph of f(x) = 4(1/2)^(x + 1) − 3?
Yintercept of (0, −1), starts up on the left, gets closer to y = −3 on the right
Yintercept of (0, −1), starts down on the left, gets closer to y = −3 on the right
Yintercept of (0, 1), starts up on the left, gets closer to y = −3 on the right
Yintercept of (0, 1), starts down on the left, gets closer to y = −3 on the right

Best ResponseYou've already chosen the best response.1to work out the y intercept put x = 0 into f(x) and work it out

Best ResponseYou've already chosen the best response.1= 4(1/2)^(0+1)  3 = 2^1  3

Best ResponseYou've already chosen the best response.1so work out some values of f(x) for negative x's like x = 2 2 f(2) = 4 (1/2)^(2+1)  3 = 4 / (1/2) 3 = 5 f(3) = 4(1/2)^2  3 = 4 / 1/4  3 = 13 so the left side of the curve will descend pretty steeply

Best ResponseYou've already chosen the best response.1for high values of x the curve will tend to approach 3 because 1/2 to a high power will approach zero and that leaved  3

Best ResponseYou've already chosen the best response.1it starts at high value of f(x) on the left so i think it starts 'up on the left' what do you think?
