If f(x) = x2 + 4x - 12, find f(2).

Illusion [34]

Answer:

-3

Step-by-step explanation:

Please write this as f(x) = x^2 + 4x - 12. "x^2" represents "the square of x."

f(2) is the value of this function when x = 2:

f(2) = f(2) = (2)^2 + 4(2) - 12 = 9 - 12 = -3

What’s the vertical and horizontal line?

coldgirl [10]

Answer:

Part 1) Vertical line : $x=1$

Part 2) Horizontal line : $y=-4$

Step-by-step explanation:

Part 1) Write the equation for the vertical line passing through the point (1,-4)

we know that

The equation of a vertical line (parallel to the y-axis) is equal to the x-coordinate of the point that passes through it

The x-coordinate is 1

therefore

The equation of the line is

$x=1$

Part 2) Write the equation for the horizontal line passing through the point (1,-4)

we know that

The equation of a horizontal line (parallel to the x-axis) is equal to the y-coordinate of the point that passes through it

The y-coordinate is -4

therefore

The equation of the line is

$y=-4$
