Answer:
A is the correct answer
Step-by-step explanation:
To answer this you need to find the value for x that makes the y value zero.
and the value for y when x is zero.
There are 2 intercepts on for a linear equation. One x-intercept (where the graph crosses the x-axis) and one y-intercept (where the graph crosses the y-axis).
Step 1:
The x-intercept is found by setting 'y' equal to zero and solving the equation.
0 = 4x - 2 solve this...
2 = 4x (add 2 to both sides)
0.5 = x (divide both sides by 4 to get x by itself)
So the x-intercept is at the point (0.5. 0)
Step 2: The y-intercept if found by setting 'x' equal to zero and solving
y = (0)x - 2
y = -2
So the y-intercept is at the point (0, -2)
[-4(-2)-8]+[-1-(-2)^3]+2(-2)^3
(8-8)+(-1+8)-64
7-64

Answer:
(fg)(x) = x^2 -2x -8
Step-by-step explanation:
(fg)(x) = f(x)·g(x) = (x +2)(x -4)
= x(x -4) +2(x -4) = x^2 -4x +2x -8
= x^2 -2x -8 . . . . matches the 3rd choice
Hi there!
h(x) = 5x + 11
To find h(7) - 3, we can substitute 7 for x and subtract 3:
h(7) = 5(7) + 11 - 3
Simplify:
h(7) = 35 + 11 - 3
h(7) = 43
