Find the value of f(3) if f(x) = 4x^2 - 8x + 3

Plug in 3 for the x values.
4*3^2-8*3+3
Then use PEMDAS
4*9-8*3+3
36-24+3
12+3=15
The answer is 15

F(3) = 4x^2-8x+3
      = 4(3^2)-8(3)+3
      = 4(9)-24+3
      = 36-24+3
      = 15

Use the PMDAS rule. Get the value of x^2 first then do the math.

The answer is 270 cars.you can do this by making a proportional relationship. for instance, 200 is the whole we are using, so on a “number line” 200 would be over 100%. now, since he sells 35% more, add 35% to 100% to get 135% on the other side of the “number line” on the bottom half, leaving the top half empty.cross multiply 200 by 135 then divide by 100 to get your answer. i hope this , if it did, , if you don’t mind, giving me brainiest! 200/100% } 200 • 135 /100 ? /135%
