What is the equation of the quadratic function with a vertex at (2,-25) and an x-intercept at (7,0)?
o f(x) = (x - 2)(x-7)
f(x) = (x + 2)(x + 7)
Of(x) = (x – 3)(x + 7)
f(x) = (x + 3)(x-7)

step-by-step explanation:

the correct answer would be c

d

step-by-step explanation:

the two points from this line are   (0,4)   & (2,-2)

we can call

now, lets find the slope (m):

now finding b (the y intercept). this is the point at the y-axis where the line cuts the axis. looking at the graph, it is y = 4. so the point is 4. hence b = 4

the slope-intercept form is given by  

putting the points, we have:

d is the correct answer.
