Can someone me with this ? ? im totally lost on this one

So first of all b is a variable and this variable has a value of 5 so replace b with 5 and imagine there is a multiplication sign between the 3 and 5 (since they are not spaced out meaning you multiply) assuming you are using order of operations on this problem you would first find 5 (b) squared (muliplyed by the power of two) and multiply that answer (the answer of 5 squared) by 3 and then take the product of the answer you just got and subtract that from 5 (b)   Assuming you are not using order of operations you would first multiply 3 by 5 (b) and it would equal 15 then take 15 and multiply it by the power of 2 and then subract b      Hope this helps you understand

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )
