Why is the answer E?

Mathematics
1 answer:
bearhunter [10]3 years ago
3 0

Step-by-step explanation:

The only way the answer could be E is if the x² term under the radical is supposed to be t².

f(x) = ∫₄²ˣ √(t² − t) dt

f'(x) = √((2x)² − 2x) (2)

f'(x) = 2√(4x² − 2x)

f'(2) = 2√(4(2)² − 2(2))

f'(2) = 2√12

yKpoI14uk [10]

Answer:

y_{max}=24

Step-by-step explanation:

Given function y=-5x+4 is linear function. This linear function represents the straight line on the coordinate plane. The slope of this line is -5. Since the slope is negative, the linear function is decreasing for all x. This means

\text{ if } x_1 f(x_2)

You ar geven the interval -4\le x\le 3. So, the maximum value of the function is at the point x=-4 and the minimum value of the function is at the point x=3.

At x=-4,

y=-5\cdot (-4)+4=20+4=24.
