Question

A: What is the y -intercept of the graph of the equation y=x2−5x+4 ?

B: An equivalent way to write this equation is y=(x−4)(x−1)
. What are the x-intercepts of this equation's graph?

Answer 1

Answer is
A) y intercept is at +4 on the y axis

B) x = 1 or x = 4

Solve each

(x - 4) and ( x - 1) = 0

x - 4 = 0
Add 4 to both sides to solve for x
x -4 + 4 = 0 + 4
Simplify
x = 4

x - 1 = 0
Add 1 to both sides to solve for x
x -1 +1 = 0 +1
Simplify
x = 1
