f(x)={[-2," if "x<=-1],[2x," if "-11]

Examine the continuity of the function f defined by f(x) = {[2x+1if x 1]:} .

1f(x)=?_(-)2 at x=1. for 1

For what value of k is the following function continuous at x=2? f(x)={[2x+1,;,x 2]}

If f(x) = ((2 + x)/(1 + x))^(1 + x) , then f'(0) is equal to

If f(x) = ((2 + x)/(1 + x))^(1 + x) , then f'(0) is equal to

For what valueof K is the following function continuous at x = 2 ? f(x)={(2x+1,when x 2):}

lim_(x rarr1)f(x), where f(x)={x^(2)-1,x 1

Find (lim)_(x rarr1)f(x), where f(x)=[x^(2)-1,x 1

Find the value of a if the function f defined by f(x) = {:{(2x-1, x 2):} is continuous at x = 2.

If f(x)=log((1+x)/(1-x)),t h e n (a) f(x_1)f(x_2)=f(x_1+x_2) (b) f(x+2)-2f(x+1)+f(x)=0 (c) f(x)+f(x+1)=f(x^2+x) (d) f(x_1)+f(x_2)=f((x_1+x_2)/(1+x_1x_2))
