Okay, so this is exponential. The formula for the exponental function is Y=ab^x
a is the y-intercept
b is the rate/ratio
x is the time
According to the graph, (remember the y-intercept is in the y-axis) so 2 is the y-intercept.
Knowing what the y-intercept is, you know what the answer is.
A.

A^2+B^2=C^2
A=B because both angles 45 degrees
5^2+5^2=C^2
25+25=C^2
x=5
y=sqrt (50)
