Answer:
The quadratic function is f(x) = (x − 2) (x − 4)
Step-by-step explanation:
Given a vertex with an x-coordinate of 3. we have to write a quadratic function in factored form that would have a vertex with an x-coordinate of 3 and two distinct roots.
As the vertex lies on the axis of symmetry, so the axis of symmetry is x = 3. Now we have to take two x-intercepts that are equal distance from the axis of symmetry i.e from point of vertex and we can use these x-intercepts to write factors of the function by subtracting from x.
we take 2 and 4 ∴ factors becomes (x-2) and (x-4)
Hence, the quadratic function is
f(x) = (x − 2) (x − 4)
Answer:
y=7x+1
Step-by-step explanation:
y-y1=m(x-x1)
y-8=7(x-1)
y-8=7x-7
y=7x-7+8
y=7x+1
