Will give

the graph of which function does not contain the point (0, 1)?

a.
y=(3/4)^x
b.
y=-2^x
c.
y=3^x
d.
y=(1/2)^x

Simplest way: sub in the coordinate into the equation.

Since they are all exponential functions, so all of them should pass through (0,1)

However, B has the minus sign, which flips the function vertically, so it passes through (0,-1)

Answer is B
