The answer is true.
Method 1:
The given function is a cubic function. And inverse of a cubic function is also a function.
Method 2:
Since the function is one-to-one function i.e it passes the horizontal line test, its function will pass the vertical line test which is a test if a relation is a function or not.
So, yes the inverse of G(x) will be a function.
Answer:
2 cm squared
Explanation:
The question asks for the area of each small triangle in the corners(meaning 1 triangle, not 4) as shown from the dotted lines. The area of a triangle is found by (base*height)/2.
Looking at the diagram, the triangle is 2 cm for both the base and height, and the hypotenuse is not labeled. Because it is a right triangle, 2 cm is also the height(the height is defined as an altitude from the tip of the triangle to the base using a right angle). So, height=2 and base=2.
Plug these numbers into the formula bh/2.
bh/2=?
(2)(2)/2=?
4/2=?
2=?
Each triangle has an area of 2 cm squared.
(30+ 25)+(25 x 12) = then put your answer but this is my way of doing it.
The picture is illegible.
Slope of line y = -9x+6 is -9
Slope of any perpendicular to line is -1/9
Point-slope equation for line of slope -1/9 that passes through (3,5):
y-5 = (-1/9)(x-3)
The equation can rearranged to slope-intercept form or standard form. (Since I can’t read the picture, I don’t know what form of equation is needed.)
