The value of the function f(x) = 3x2 − 2x for x = 4

40

Step-by-step explanation:

Evaluate 3 x^2 - 2 x where x = 4:

3 x^2 - 2 x = 3×4^2 - 2×4

4^2 = 16:

3×16 - 2×4

3×16 = 48:

48 - 2×4

-2×4 = -8:

-8 + 48

| 4 | 8

- | | 8

| 4 | 0:

 40

region b will make the inequalities y < 2x + 1 and y > -x - 2 true ⇒ answer a

step-by-step explanation:

* lets study the graph and the inequality to solve the question

- the inequality y > -x - 2

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = -2 that means the line intersect the y-axis at point (0 , -2)

∵ the sign of the inequality is >

∴ we shad the part over the line

  region a and b

- the inequality y < 2x + 1

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = 1 that means the line intersect the y-axis at point (0 , 1)

∵ the sign of the inequality is <

∴ we shad the part under the line

  region b and c

∵ the common region between the two lines is region b

∴ region b will make the inequalities y < 2x + 1 and y > -x - 2 true

a: inscribed angles
