Answer:
Step-by-step explanation:
Hello! First step is setting up our given equation for f(d).
f(d) = 5d - 4
Next, we see that we need to evaluate f(3), which just means we substitute 3 for d.
f(3) = 5(3) - 4
Simplify:
f(3) = 15 - 4 = 11
Therefore, f(3) = 11
Next we will substitute -3.3 for d.
f(-3.3) = 5(-3.3) - 4
Simplify:
f(-3.3) = - 16.5 - 4 = - 20.5
Therefore, f(-3.3) = -20.5
Now, we see that we need to substitute b for d.
f(b) = 5b - 4
And that's all the simplification we can do.
