Answer:
y=-5x-5
Step-by-step explanation:
The line contains points at (-2,5) and (0,-5)
(y1-y2) / (x1-x2) = slope
(-2,5) =(x1,y1)
(0,-5) = (x2,y2)
(5--5) / (-2-0)
10 / -2 = -5
y= -5x + b
plug in points for x and y to find b
5=-5(-2)+b
5=10+b
-5=b
y=-5x-5
Answer:
14
Step-by-step explanation:
note that (f - g) = f(x) - g(x)
f(x) - g(x) = 3x² + 1 - (1 - x) = 3x² + 1 - 1 + x = 3x² + x
To evaluate (f - g)(2) substitute x = 2 into f(x) - g(x)
(f - g)(2) = 3(2)² + 2 = (3 × 4) + 2 = 12 + 2 = 14
