Answer:
h=0.6, -0.6
Step-by-step explanation:
take the root of both sides and solve
Follow the "<em>y = mx + b</em>" formula, in which "m", stands for slope, and "b" stands for y-intercept
m = slope
m is located to the left attached to x.
-2 is in the place of m, therefore, -2 is the slope of the equation given.
-2 is your answer
hope this helps
Answer:
f(f(x)) = 27
+ 18x² + 4
Step-by-step explanation:
To find f(f(x)) substitute x = f(x) into f(x) , that is
f(3x² + 1)
= 3(3x² + 1)² + 1 ← expand parenthesis using FOIL
= 3(9 + 6x² + 1) + 1 ← distribute parenthesis by 3
= 27 + 18x² + 3 + 1 ← collect like terms
= 27 + 18x² + 4
Actually looks like c.
Basically you can't divide by 0 so x= -2 and x= -1 are the values excluded from the domain. The others are good.
