Answer:
Step-by-step explanation:
F(x)=-x+5
So
f(-4)= -(-4)+5
f(-4)= 4+5
f(-4)= 8
Only we have to substitute value of x then after simplification we will get answer..Hope this will help
Answer:
∠ 1 = 120°
Step-by-step explanation:
Note that ∠ Q and ∠ R are congruent, that is both 30°, thus
∠ 1 = 180° - (30 + 30)° = 180° - 60° = 120°
Answer:
1250
Step-by-step explanation:
i hope this helps
Answer:
It does not have any angles that exceed 90 degrees
Step-by-step explanation:
Answer:
The domain is 
and its range is 
The y-intercept is (0,3).
Step-by-step explanation:
Consider the parent function 
Its domain is 
and its range is 
The graph of the function 
is obtained from the graph of parent function by translation 3 units up (see diagram). This translation doesn't change the domain and will change the range of the function, thus the domain is and its range is
To find th y-intercept you have to find y at x=0:
Hence, the y-intercept is (0,3).
