Question

Given the function r(x)=-2/3x+4, find each value r(-6)

Answer 1

$r(-6)=-\frac{2}{3}(-6)+4=4+4=\boxed{8}$

Answer 2

The value of r(x) at f(- 6) = 8.

We have the function r(x) = $-\frac{2}{3} x + 4$

We have to find the value of r(x) at x = - 6.

If f(x) = 5x + 3, then find the value of f(-2).

Substitute x = - 2 in the value of f(x) -

f(-2) = 5 (-2) + 3 = - 10 + 3 = - 7.

According to question, we have -

f(x) = $-\frac{2}{3} x + 4$

Substitute r = -6 in f(x), we have -

f(-6) = $\frac{-2}{3} \times -6 + 4$

f(-6) = - 2 x - 2 + 4

f(-6) = 4 + 4 = 8

Hence, the value of f(x) at f(- 6) = 8.
