Answer:
The graph not have x-intercepts
Step-by-step explanation:
we know that
The x-intercept is the value of x when the value of y is equal to zero
we have

This is the equation of an absolute value in vertex form open upward
The vertex is the point (2,12)
The y-coordinate of the vertex is above the x-axis and the graph open upward
That means ----> The graph do not intersect the x-axis
therefore
The graph not have x-intercepts
<u><em>Verify</em></u>
For y=0
substitute in the equation

----> is not true
The left side of the equation cannot be a negative number
so
The equation not have solution for y=0
therefore
The graph not have x-intercepts
see the attached figure to better understand the problem
Answer:
B. Yes, because it passes the vertical line test.
Step-by-step explanation:
B. Yes, because it passes the vertical line test.
A vertical line going from left to right will intersect at most one point on the graph at a time. That makes it a function.
Simplifying
f(x) = x2 + 8x + -3
Multiply f * x
fx = x2 + 8x + -3
Reorder the terms:
fx = -3 + 8x + x2
Solving
fx = -3 + 8x + x2
Solving for variable 'f'.
Move all terms containing f to the left, all other terms to the right.
Divide each side by 'x'.
f = -3x-1 + 8 + x
Simplifying
f = -3x-1 + 8 + x
Reorder the terms:
f = 8 + -3x-1 + x
