x-intercept means f(x) = 0
(x-8)(x+9) = 0 ⇒ x = 8 or x = - 9
There are two points which are x-intercepts. They are (8,0) and (-9,0).
Answer:
f(4) = 1
Step-by-step explanation:
f(4) = what?
So if we know that x, aka 4, is technicially f is greater then 2, so you can plug in x as 4. So that means 5(4) - 19 = 20 - 19 = 1, so f(4) = 1
False !! but opposite can be true !!
Answer:
Yes
Step-by-step explanation:
Plug in (-1 , -2) in the LHS of the equation.
2x - 3y = 2*(-1) - 3*(-2)
= -2 + 6
= 4 = RHS
So, (-1 , -2) is a solution
