I need the answer and show work for this question

Step-by-step explanation:

f(x) = -2x² + 8x

f(3) = -2*(3)² +  8*3

     = - 2*9 + 24

     = - 18+ 24

f(3) = 6

f(1)= -2*(-1)² + 8*(-1)

   = -2*1  - 8

  = - 2 -8

f(1) = -10

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

we have the parent function given by,

1. the function is translated 5 units to the left.

so, we get,   becomes

2. the function is translated 5 units to the right.

so, we get,   becomes

3. the function is translated 5 units upwards.

so, we get,   becomes

4. the function is translated 5 units downwards.

so, we get,   becomes

5. the function is reflected across x-axis.

so, we get,   becomes

6. the function is reflected across y-axis.

so, we get,   becomes .
