Question

Evaluate the function f (x) = 4 • 7x for x =-1 and x = 2. Show your work.

Answer 1

this means that wherever we see x we plug in x = -1

Answer 2

\[f(x) = 4*7x = 28x \]

essentially,

\[f(x) = 28x \]

Answer 3

now to find f(2) the value of the function when x =2

we plug in 2 for x

\[f(2) = 28(2) = ? \]
