Answer: Wouldn't the answer be A?
Step-by-step explanation:
The answer is 43 hope this helps:)
You just substitute the value of x in the given equation:
f(x) = 2x^2 - 5
f(-4) = 2 (-4)^2 -5 = 27
f(x) : a name given to the equation
f(-4): refer to the equation when the value of the independent variable x has the value between the brackets.
196 3/8 in^3. To get this, multiply all the numbers together. To find volume, the equation is length x width x height.
It is not factorable. Factors of 21 are. 21 and 1
7 and 3. None of those add up to 12
