Answer:
f(-2) = -1
f(0) = -5
f(4) = -1
Step-by-step explanation:
The number inside of f( ) is telling you which equation to use to get the answer.
Example:
f(-2) since -2 is less than 0 you would use (x^2) - 5. So, ((-2)^2) - 5 = 4-5 = -1
f(0) since 0 is less than or equal to 0 you would use (x^2) - 5 again. So, ((0)^2) - 5 = 0-5 = -5
f(4) since 4 is grater than 3 you would use (2^(x-1)) - 9. So, (2^(4-1)) - 9 = -1

Answer: - 9/8
Step-by-step explanation:
The equation of a line is y=mx+b
To find the gradient you calculate the change in Y/change in X.
To find the y-intercept you should plug it in a graphic calculator.
Answer:
137
Step-by-step explanation:
175+115+145+115+135= 685
685÷5= 137
To put that into words you add up all the numbers and divide the sum by how many numbers there are.
