Answer:
2.5
Step-by-step explanation:
f'(x) is non-negative, so f(x) is monotonic and increasing. Its minimum value on the interval of interest will be less than f(0) by the amount of the integral of f'(x) from -3 to 0.
That integral is the area of the triangle bounded by the portion of the curve from (-3, 3) to (0, 0) and the x-axis. The area is ...
A = (1/2)bh = (1/2)(3)(3) = 4.5
So, ...
f(-3) = f(0) -4.5 = 7 -4.5
f(-3) = 2.5
_____
The red curve in the attached graph is f(x). Its value at -3 is 2.5.
Answer:
3(3d³ - 4a²)
Step-by-step explanation:
We have to factorize the algebraic expression as 9d³ - 12a².
Now, we have to take common the equal term from both the part of the expression for the purpose of factorization.
But, the only common term among the two terms from the expression is 3.
Therefore, the required factorization is 3(3d³ - 4a²). (Answer)
Answer:
8x^4 - 28x^3 + 4x^2.
Step-by-step explanation:
4x(2x^3 - 7x^2 + x)
= 4 * 2x^3 + 4x*-7x^2 + 4x*x
= 8x^4 - 28x^3 + 4x^2.
