Step-by-step explanation:
70/7 this equal the the speed elsise travels in one hour
32x7 this equals the total distance elsise travels in 32 hours
Slope of the vertical line: undefined
Equation of the vertical line: x=5
f(x)+g(x) = 3x^2-x-4
f(x)-g(x) = 4x^2-7x-4
Foil (2x-6)(5x+1) = 10x^2-28x-6
The roots (zeros) of the parabola are -2 and 3
X-coord for vertex = -1/2
Last problem: s^2 + 4s
