Find the value of x for which the graph of y = 3x^2 - 8x + 7 achieves its minimum y-value.​
gulaghasi [49]

Answer:

<h3>The y value achieves its minimum at x = 4/3</h3>

Step-by-step explanation:

Given the graph of y to be 3x² - 8x + 7, to get the value of x for which the graph function achieves its minimum y value, we need to find its turning point first.

At the turning point, dy/dx = 0

Given y = 3x² - 8x + 7

\frac{dy}{dx} = 6x-8\\ at\ turning\ point\ 6x-8 = 0

6x = 8\\x = \frac{8}{6}\\ x =\frac{4}{3}

The y value achieves its minimum at x = 4/3

use the intermediate value theorem to determine, if possible, whether g(x)=2x^3+3x^2-3x+4 has a real zero between -2 and -1
inn [45]

Answer:

Step-by-step explanation:

g(-2)=2(-2)^3+3(-2)^2-3(-2)+4=-16+12+6+4=6

g(-1)=2(-1)^3+3(-1)^2-3(-1)+4=-2+3+3+4=8

it does  not change sign ,so there is no real zero between -2 and -1.
