By graphing the given options as shown in attached figure
<span>f(x) = (1/4)^x+2 ⇒⇒⇒⇒ The black graph
f(x) = (1/4)^x +2 </span><span>⇒⇒⇒⇒ The red graph
</span>
f(x) = (1/4)^x-2 <span><span>⇒⇒⇒⇒ The blue graph
</span></span><span><span />
f(x) = (1/4)^x -2 ⇒⇒⇒⇒ The green graph
</span>
The correct answer will be the blue graph
Answer:
z = 5
Step-by-step explanation:
m = ∆y/∆x = y₂-y₁/x₂-x₁
0 = y₂-y₁/x₂-x₁ = 5 - z / -7 - 9 = 5 - z / -16 →
5 - z / -16 = 0 → 5 - z / -16 × -16 = 0 × -16 → 5 - z = 0 →
5 - z - 5 = 0 - 5 → -z = -5 → z = 5
Answer:
put x=-1, and the rest will be easy
Step-by-step explanation:
When x=-3, then
- (-3)²-5×(-3)-8
- 9+15-8
- 24-8
- 16
