Answer:
7
Step-by-step explanation:
We need to plug in -1 for x. Here's what we get:
multiplying two negative numbers gives us a positive number
= 7
F(x) = 2x^2 + 5x
f(3b) = 2(3b)^2 + 5(3b) = 2(9b^2) + 15b = 18b^2 + 15b
B & C would be your answer because 3^-3 would turn into a fraction, 1/3^3 which is the same as C.
Ok. the lost 7 shortstop cards will be -7, and the 5 gained pitcher cards will be a positive 5. So, 5+(-7), or 5-7= -2
