Exercise 74 Page 303

Calculate the function's value when by substituting $- 2$ for $x$ in the equation.

$- 11$

Practice makes perfect

Using the function

f (x),

we want to evaluate for the given value,

f (- 2) .

To do this, we need to substitute

- 2

for

x

in each instance of the

x -

f (x) = 4 x - 3

$x = - 2$

f (- 2) = 4 (- 2) - 3

$a (- b) = - a \cdot b$

f (- 2) = - 8 - 3

Subtract term

f (- 2) = - 11
