For f(x) = 8x – 9, find f(-3)?
回答 (5)
✔ 最佳答案
OK
f(x) = 8x - 9
f(-3) = 8(-3) -9
= -24 -9
= -33
Hope that helps.
f(x) = 8x - 9
f(-3) = 8(-3) - 9
f(-3) = -24 - 9
f(-3) = -33
Okay, so if f(x) = 8x - 9, you must replace x with - 3 wherever it appears in the function in order to get f(-3):
f(-3) = 8(-3) - 9
= -33 (final answer)
Hope this helps!
Just replace x with -3 in the equation, f(-3)=8(-3)-9=-24-9=-33
f(-3)= 8(-3)-9=
=-24-9=
=-33
f(-3)=-33
