Answer:
D
Step-by-step explanation:
Given that f(x) has domain { 2, 4, 7 }
Substitute the values from the domain into f(x) for the range
f(2) = 2² - 5 = 4 - 5 = - 1
f(4) = 4² - 5 = 16 - 5 = 11
f(7) = 7² - 5 = 49 - 5 = 44
Thus the range is { - 1, 11, 44 } → D
Answer:
-12
Step-by-step explanation:
I am assuming that you want (f*g)(4), which is the product of f and g at x = 4.
If this is actually the case, then one way to evaluate (f*g)(4) is to find f(4) and g(4) separately and then multiply the results together. This gives us
f(4)*g(4) = (8 + 4)*(-4 + 3) = -12
You just answerd it yourself i think.......
