Step-by-step explanation:
<u><em>Explanation</em></u>:-
Given that the vector < 3 , -7 >
Given the vector reflection across the x-axis
(x,y) → (x , -y)
The vector < 3,-7> →< 3, -(-7)>
< 3,-7> →< 3, 7)>

Step-by-step explanation:
Answer:
(f.g)(x)=4x^3+4x^2
Step-by-step explanation:
f(x) = 4x^2and g(x) = x+1, (f•g)(x)=?
(f.g)(x)=f(x)*g(x)
(f.g)(x)=4x^2*(x+1)
(f.g)(x)=4x^3+4x^2
hope it helps. .brainliest please
Sqrt[x] = -x
x= x ^ 2
x - x^2 = 0
-x(x-1)=0
x(x-1)=0
x = 1 or x = 0
sqrt 1 isn not equal to 0
x= 0
