Consider the function f(x) = x2 + x + 2. What is the value of f(- 6)?
À -40

f(-6) = 32

Step-by-step explanation:

f(x) = x² + x + 2

for f(-6), x = -6 (substitute this into f(x) )

f(x) = x² + x + 2

f(-6) = (-6)² + (-6) + 2

= 36 - 6 + 2

= 32

The value of b is 4.

Step-by-step explanation:

First, find the y-intercept.

y = mx + b

-8 = -2(5) + b

-8 = -10 + b

2 = b

So now our equation is y = -2x + 2. Now plug in the values.

y = -2(-1) + 2

y = 4
