Hello from MrBillDoesMath!
Answer:
f(-1) = 2
f(1) = 6
f(2) = 11
Discussion:
Let f(x) = 2x^3 - 3x^2 + 7. Then
f(-1) = 2 (-1)^3 - 3 (-1)^2 + 7 = -2 -3 + 7 = -5 + 7 = 2
f(1) = 2(1)^3 - 3(1)^2 + 7 = 2 -3 + 7 = -1 +7 = 6
f(2) = 2(2)^3 - 3(2)^2 + 7 = 2*8 - 3*4 + 7 = 16-12+7 = 11
Thank you,
MrB
Which ordered pairs are you looking for ? When looking at a number line remember that an ordered pair goes in this direction (x,y) so therefore if it was (1,3) you’d go right 1 and up 3 . It’s always right and then up . Think of it as you crawl before you can actually stand up !

Answer:
Linear function.
Step-by-step explanation:
y=2x-6 is a linear function, because it follows the format, y=ax+b, where a=2 and b= -6.
