Answer:
5
Step-by-step explanation:
h(x) = x² + 1
k(x) = x - 2
(h - k)(3)
Plug x as 3.
h(3) - k(3)
3² + 1 - 3 - 2
Evaluate.
9 - 4
= 5
Answer:
-23
Step-by-step explanation:
I just did 8+15=23 but made it negative. so you can do
-23+8= -15
This is a special case. If after step two I would've gotten y=something... I would have plugged that new y value into my first equation
Answer:
It's the first option.
Step-by-step explanation:
y = cos x transformed to cos (x - π/2) moves the graph π/2 units to the right.
Multiplying by 3 to give 3 cos(x - π/2) stretches the graph 3 units parallel to the y-axis and adding 3 to this moves the graph up 3 units.
So the required equation is y = 3(cos x - π/2) + 3.
