Question

If k(x) = b x and k(a) = 0.2, which option below gives the value of k(–3a)?

Answer 1

Answer:

k(–3a)=-0.6

Step-by-step explanation:

If k(x) = b x and k(a) = 0.2

We need to find out k(-3a)

To find out k(-3a) we multiply k(a) by -3

For example k(ca) = c*k(a)

where c is a constant

So to find k(-3a) we multiply -3 with k(a)

k(-3a) = -3 * k(a)

Replace k(a) with 0.2

k(-3a)= -3 * 0.2= -0.6

Answer 2

The answer is -0.6a because multiplying pos and neg equals neg thats why its a neg
