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

The linear equation that satisfy the data in the table is: A. y = −4x − 4.
<h3>How to Find the Linear Equation for a Data in a Table?</h3>Given the table attached below, find the slope (m) = change in y / change in x using two pairs of values, say, (-1, 0) and (0, -4):
Slope (m) = (-4 - 0)/(0 - (-1)) = -4/1 = -4
Find the y-intercept (b), which is the value of y when x = 0. From the table, when x = 0, y = -4.
b = -4.
Substitute m = -4 and b = -4 into y = mx + b
y = -4x + (-4)
y = -4x - 4
The equation that satisfy the data is: A. y = −4x − 4.
