Use the function f(x) = 2x3 - 3x2 + 7 to complete the exercises. f(−1) = f(1) = f(2) =

Step-by-step explanation:

The value of the function f(x) at x=a can be determined by substituting a instead of x into the function expression.

1. When x=-1, then

f(-1)=2\cdot (-1)^3-3\cdot (-1)^2+7=-2-3+7=2.

2. When x=1, then

f(1)=2\cdot 1^3-3\cdot 1^2+7=2-3+7=6.

3. When x=2, then

f(-1)=2\cdot 2^3-3\cdot 2^2+7=16-12+7=11.

f(-1)=2

f(1)=6

f(2)=11

Step-by-step explanation:

The given function is

Substitute x = -1 to find the value of f(-1)

Thus, f(-1)=2

Substitute x = 1 to find the value of f(1)

Thus, f(1)=6

Substitute x = 2 to find the value of f(2)

Thus, f(2)=11

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
