Given:
The parent function is

To find:
The function after the reflection over the x-axis.
Solution:
We know that, if a function f(x) reflected over x-axis to get the function g(x), then

Putting
, we get


The function after the reflection over the x-axis is
.
Therefore, the correct option is B.
(A) a triangle whose angles each measure less than 90°
Answer:
-3x+6
Step-by-step explanation:
-3x-6(-1)
First, multiplying two negatives equals a positive: (-)×(-)=(+). Then,
multiply the numbers -3×+6×1 = -3x+6. Then, you got the answer and the answer is -3x+6
Intersect with x axis indicates that x value would be Zero
Thus when x = 0
y would be
y = -18
Therefor intersection would be at (0,-18)
Answer:
Step-by-step explanation:
Bottom triangle
Area = b * height
b = 4 + 4 = 8 cm
h = 5.75
Area = 1/2 * 5.75 * 8
Area = 23 cm^2
Trapezoid
b1 = 8
b2 = 4
h = 2
Area = (b1 + b2)*h/ 2
Area = (8 + 4)*2 /2
Area = 12
Total area = 23 + 12
Total area = 35
