Answer:
f(- 2) = - 4
Step-by-step explanation:
Step-by-step explanation:
To evaluate f(- 2) substitute x = - 2 into f(x) , that is
f(- 2) = (- 2)² + 3(- 2) - 2 = 4 - 6 - 2 = - 4
Remember PEMDAS.
P=parenthesis
E=exponents
M=multiplication
D=division
A=addition
S=subtraction
Answer:
Step-by-step explanation:
For 
the set of points that include all solutions are 
such that ; then we have 
.
What is important to stress here is that represents all of the solutions, while other points that we are given represent one solution (for example, point (2,-1) is just one solution)
This value is in the positive quadrant meaning that all values remain positive. To answer this problem you must have an understanding of trig ratios being that tangent is opposite/adjacent. When you plot the points and draw a triangle using the origin of the point, you find that the adjacent value is 5 and opposite value is 15
