Answer:
f(3) is - 1
Step-by-step explanation:
f(3) means the function value when x = 3
3 is in the domain, the function value is in the range.
Thus when x = - 3 → y = - 1
f(3) is - 1
5x-7
Pls mark me brainliest
Answer:
a) t=5
5+5+5=15
b) x=11
11-8=3
or you can add 3 to both sides and x=11
c) w=3
7(3) = 21
21+3=24
or subtract 3 from both sides to get 7w=21
then divide by 7 on both sides to get w=3
