Question

Find k so that the following function is continuous on any interval:

f(x)=kx if 0<=x<3 and f(x)=8x^2 if 3<=x

K=?

Answer 1

for x=3, the right piece of the function has value 72..
so to make this continuous, the left piece must have a value of 72 also...
so,
kx = 72
k(3) = 72

can you take it from here?

Answer 2

yup thanks

Answer 3

yw...:)

Answer 4

wait im lost plz continue ?

Answer 5

3k = 72
