Answer:
The correct option are;
On a coordinate plane, a cubic function has an x-intercept of (0, 0)
On a coordinate plane, an oval is in quadrant 1
Step-by-step explanation:
Rotational symmetry of a shape is a shape that when it is rotated on its axis to a given angle less than one complete revolution, the shape looks exactly like the pre-image or original appearance of the shape
For a cubic function that has x-intercept = (0, 0) we have;
y = f(x) = a·x³ + b·x² + c·x
Has the shape f a fan blade and therefore, looks the sane when rotated when rotated through 180°
The shape of an oval looks the same when rotated through 180°
Yes, it’s a function because there is no repeating x-values,
The area of the rectangular part = 14 x 20 = 280 sq. cm
The area of the half circle = 1/2 (3.14 x 7^2) = 76.9 sq. cm.
Total area = 280 + 76.93 = 356.9 cm^2
We can write the function in slope-intercept form (y + mx + b). Since we have the slope, we can solve for the y-intercept.
y = -2x + b
4 = -2(0) + b
4 = b
Input the data we have now.
y = -2x + 4
Since we are dealing with a function switch out the y for f(x)
f(x) = -2x + 4
Best of Luck!
