You can put this solution on YOUR website! At which point does the graph of f(x)=x^2+3x-18 intersect the x-axis?
.
This will occur where:
0=x^2+3x-18
Note: setting it to zero
.
Now, we solve for x
0=x^2+3x-18
factoring the right:
0=(x+6)(x-3)
Therefore,
x = {-6, 3}
.
Conclusion:
intersects the x-axis at
(-6,0) and (3,0)
