Question

how are tangents useful in determining the value of e?

a. The number e is defined in the tangent to y=3^x whose slope is approx. 2.71828
b. The slope of the tangent to the function y=2^x equals e at the point where x=0
c. The slope of the tangent to the function y=a^x at x=0 equals 1 where a=e
d. The slope of the tangent to the function y=a^x at the x=0 equals e when a=3

Answer 1

c. The slope of the tangent to the function y=a^x at x=0 equals 1 where a=e
