Hi there!
To find f(-2), we need to plug in the value x = -2 into the equation.
Remember that multiplying a negative by a positive ends up with a positive.

Answer) $23
Explanation)
10 x 2.29 = 18.9
1.89 + 1.89 = 3.78
18.9 + 3.78 = 22.68
Answer:
y = m x + b is the standard form of a straight line
m = (y2 - y1) / (x2 - x1) = (10 - (-8)) / (-3 - 0) = 18 / -3 = -6
When x = 0 y = b from the equation for a line
y = - 8
So our equation is
y = -6 x - 8
As a check let x = -2 then
y = (-6 * -2) - 8 = 12 - 8 = 4
Check on the graph to verify that this equation holds
Answer: his percent of increase = 66.66%
Step-by-step explanation:
percent of increase = Increase/ Previous goal x 100
Previous goal = 3 goals
Yesterday's goal = 5 goals
Percent of increase = (5-3) / 3 x 100
=2/3 x 100
=0.6666 x 100
=66.66%
