Answer:
f(-2) = g(-2) the last answer
Step-by-step explanation:
From the graph the two lines intersect each other at the point (-2 , 4)
Then when x = -2 for both functions you will find y = 4
That means f(-2) = 4 and g(-2) = 4
∴ f(x) = g(x) = 4 at x = -2
Answer:
x=3
Step-by-step explanation:
(-11)^x * (-11) ^4 = (-11)^10/ (-11)^3
We know a^b * a^c = a^(b+c)
(-11)^(x +4) = (-11)^10/ (-11)^3
We know a^b / a^c = a^(b-c)
(-11)^(x +4) = (-11)^(10 -3)
(-11)^(x +4) = (-11)^(7)
The bases are the same so the exponents are the same
x+4 = 7
Subtract 4 from each side
x+4-4 = 7-4
x =3
Answer:
<h3>27</h3>
Step-by-step explanation:
Given
f(x)= x^2-2 and g(x) = 4f (x)-1
g(x) = 4(x^2-2) - 1
g(x) = 4x²-8-1
g(x) = 4x²-9
Get g(-3):
g(-3) = 4(-3)²-9
g(-3 = 4(9) - 9
g(-3) = 36-9
g(-3) = 27
