Question

Given f(x)=3x2−6x−1 .

Answer 1

Answer:

substitute x = -23 into equation

Step-by-step explanation:

f(x) = 3x2-6x-1

this i interpret as 3 multiplied by 2. So, if you have inputted it wrong , not my fault, so here goes:

f(x) = 6 -6(x) -1

substuting x = -23 ito f(x) , we get

f(-23) = 6 - 6 (-23) -1

f(-23) = 6 + 138 -1

f(-23) = 6 + 137

f(-23) = 143
