If the function is: f(x) = 4^x - 8
D = {XeR}
R = {YeR|Y≥0}
if the function is: <span>f(x)=4^(x-8)
</span>D = {XeR}
R = {YeR|Y≥ -8}
<span>30.96576 because the calculator says so..lol

Answer:
Question 1: RS=47
Question 2: x=6
Step-by-step explanation:
Question 1:
Step 1: 3x+5=2x+15+6x-37
Step 2: 3x+5=8x-22/2
Step 3: 3x+5=4x-11
Step 4: x=16
Step 5: 2(16)+15=32+15=47
<u>RS= 47</u>

Question 2:
Step 1: 7x+2+25x-14=180
Step 2: 32x-12=180
Step 3: 32x=192 (divide 32 from each side)
<u>x=6</u>

Answer:
vertex = (3,24) Axis of symmetry = 3
Step-by-step explanation:
Use the vertex formula to find x: x=-b/2(a)
x= 12/2(2) = 3 (this is your axis of symmetry)
Substitute 3 for x in the equation to get y: y = 42
Once you have both x and y you have your vertex.
