Answer:
Answer:
f(x) = 5 + 2x
y+4x^2-1 is the same as y=-4x^2+1, then replace y with f(x); f(x)=-4x^2+1. After you do that, replace x with 2; f(2)=-4(2)^2+1. 2^2=4, 4 times -4=-16, -16+1=-15. So f(2)=-15.

=(460×5%)×3
Trina will owe her friend
=460+(460×5%) ×3
=460+23×3
=460+69
=$529
hope it helps!
Answer:
i got 1.23 don't think its right though so someone check me
Step-by-step explanation:
Use the substitution method
Answers :
g(x)= -3x+1
a. g(10)= -3(10)+1
Mutiply first = -30
-30+1= -29
<em>g(10)= -29</em>
b. g(-2)= -3(-2)+1
Negative sign and negative sign = positive sign
-3(-2)= 6
6+1= 7
<em>g(-2)= 7</em>
a.
f(x)=x^2+7
f(3)= 3^ 2+7
3*3 because of the exponent. 3*3= 9
9+7= 16
<em>f(3)= 16</em>
d.
f(a)= a^2+7
a*a= a^2
a^2+7
<em>f(a)= a^2+7</em>
The -3 at the end of the equation would be the location of the lower point on the Y axis
and since the x-4 part is in between the vertical lines, that means the absolute value, which is always positive so the graph would make a V shape
so the correct graph would be D
