Find the x-intercepts for the parabola defined by this equation:

y= –2x² - 4x + 6

Write your answer as two ordered pairs:

(x1,y2), (x2, y2)

Separate the values with a comma. Round, if

necessary, to the nearest hundredth.

b is the answer that makes most sense

step-by-step explanation:

the anwser is d) 75°

step-by-step explanation:

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.
