Answer:
Y intercept (0,2)
X intercept (3, 0)
Step-by-step explanation:
The y intercept is the value when x = 0 (or where it crosses the y axis)
Y intercept (0,2)
The x intercept is when y =0 ( or where it crosses the x axis)
X intercept (3, 0)
Rule: If x-k is a factor of p(x), then p(k) = 0. This is a special case of the remainder theorem.
Using that rule, we can see that x+5 is really x-(-5) so k = -5.
Therefore,
p(k) = 0
p(-5) = 0
so the answer is choice D.
Plug in 83 for y and 3 for x
83 = 3^2 - 6 (3) + 92
83 = 9 - 18 + 92
83 = -9 + 92
83 = 83 so it works
Hello,
The method is to find the roots of the denominator.
x²-2x-15=x²+3x-5x-15=x(x+3)-5(x+3)=(x+3)(x-5)
Roots are x=-3 and x=5
Answer C
Answer:
-3, 4
Step-by-step explanation:
(x+3)(x-4)=0
Therefore, x + 3 = 0 and x - 4 = 0
so, x = -3 and x = 4
