Question

How to solve k(a)=4a + 2: find k(a-3)

Answer 1

K(a)=4(-3)+2

K(a)=-12+2

K(a)=-9

Answer 2

If you meant to say k=(-3)

First thing you would do is plug in the (-3) to a

Your equations would look like this:

k(a) = 4(-3) + 2

You would multiply 4 × -3, giving you -12.

k(a) = 12 + 2

Then you would add 12 + 2, giving you 14.

k(a) = 14

k(a) would equal 14.
