Answer:
Since this is time and cost, we have no need for negatives, so we begin our graph at the origin (0, 0). At 0 minutes, the cost would be $2.00, so 2 is our y-intercept. For each successive minute, the cost goes up $3, so we go from (0, 2) to (1, 5), then to (2, 8), etc.n:
BRAINLIEST HACKS :))))) LOLO
Answer:
(x-4)(x+5) or x^2+x-20
Step-by-step explanation:
If a root of the function is 4, (meaning that when y=0, x=4) it can be rewritten as x-4.
The same goes for if a root is -5. it will simplify to x+5.
These are called factors of a quadratic equation.
Put together, they look like (x-4)(x+5). Using the FOIL method, that can be simplified to x^2+x-20
