Answer:
f(4) = 24
Step-by-step explanation:
Plug in 4 for x in the equation:
f(x) = x² + 3x - 4
f(4) = (4)² + 3(4) - 4
Remember to follow PEMDAS. PEMDAS =
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction
and is the order of operation.
First, solve the power:
(4)² = 4 * 4 = 16
Next, multiply 3 with 4:
3 * 4 = 12
Next, combine the terms:
f(4) = 16 + 12 - 4
f(4) = (16 + 12) - 4
f(4) = 28 - 4
f(4) = 24
f(4) = 24 is your answer.

Answer:
(x+9)^2 + ( y-2) ^2 = 25
Step-by-step explanation:
The equation of a circle can be written as
(x-h)^2 + ( y-k) ^2 = r^2 where ( h,k) is the center and r is the radius
(x--9)^2 + ( y-2) ^2 = 5^2
(x+9)^2 + ( y-2) ^2 = 25
