1. f(-6)=12
2. k(-4)=-68
Further explanation:
We have two functions whose values we have to find on certain points.
In order to find the values of function, the value is put in place of variable in the function.
So,
<u>1. f(a) = -2a</u>
We have to find, f(-6)
So putting -6 in function
<u>2. k(x) = -3x^2+5x</u>
We have to find, k(-4)
So putting -4 in function
