In the usual sense, it has no inverse function. Since it is not an injection (f(0)=f(2)=0), an inverse function would have to map 0 both to 0 and 2, and that’s impossible.
However, if you restrict the domain to [1,+oo> (to make it injective), and the codomain to [-1,+oo> (to make it surjective), then it has an inverse function, given by g(y)=1+sqrt(y+1).
A is incorrect - In decimal form, 7/5 is 1.4
B is incorrect - In decimal form, 7/4 is 1.75
D is incorrect - In decimal form, 7/2 is 3.5
The answer is C. 7/4; In decimal form, 7/4 is 2.33333333.... (this represents a terminating decimal)
Answer:
3054cm rounded to the whole number
Step-by-step explanation:
4/3xxr^3
would become 4/3 x x 9^3
once you do all of the math you get 3054 cm.
Answer:
40 ft²
Step-by-step explanation:
Divide the figure into 2 rectangles and find their areas.
The area of the smaller rectangle
= 3 × 4
= 12 ft²
The area of the larger rectangle
= (8-4) × 7
= 28 ft²
The area of the figure
= 12 + 28
= <u>40 ft²</u>
