Could anyone help with this tyy! Part IV: Sketch the graph of y = x2 - 9x + 20. Identify the vertex and x- and y-
intercepts on your sketch. (3 points)

intercepts

y = x^2 - 9x + 20

y = (x - 5)(x - 4)

x-ints at (5, 0) and (4, 0)

y = (0 - 5)(0 - 4)

y = 20

y-int at (0, 20)

vertex

y = 1x^2 - 9x + 20

-b / 2a = 9/2(1)

vertex (4.5, y)

y = (x - 5)(x - 4)

y = (4.5 - 5)(4.5 - 4)

y = -0.5(0.5)

y = -0.25

vertex (4.5, -0.25)

i recommend using desmos if in the future you need help

i can you with this sweetie!

step-by-step explanation:

the red lines denote the population of the bacteria after 35 hours. that would be 2,409.24. the y-intercept is the blue line which is 800 because that is the starting point. the equation used to make the graph is 800(1.032)^h, where h is the number of hours.
