Answer: Replace the x with the number or expression.
Given the function f (x) = 3x - 5, find f (4). ...
Find the value of h (b) = 3b2 - 2b + 1 when b = -3. ...
Find g (2w) when g (x) = x2 - 2x + 1.
Step-by-step explanation:
Answer:
x=2*sqrt(5)
Step-by-step explanation:
Since the triangle is isosceles, the other side of the triangle is sqrt(10) too. By using Pythagoras theorem, we have 10+10=x^2, x=2*sqrt(5).
Answer:
15feet squared
Step-by-step explanation:
Area= Length x height
= 5x3
= 15feet squared
Let’s see! Substituting 3 for x and -1 for y:
(3 + 1)^2 + (-1 - 1)^2 = 16
4^2 + (-2)^2 = 16
16 + 4 = 16
20 = 16
20 is clearly not equal to 16, so we know the point (3, -1) can’t lie on that circle.
Answer:
D) g(x) = 4x^2 because the given point works when it's plug in the equation.
Step-by-step explanation:
It's a vertical stretch so a>1 for the transformation
Definitely not C, since it's a shrink with 0<a<1.
Plug in the point to see which one works
g(x) = 16x^2
g(1) = 16. A is not right
B is the same thing to A
g(1) = (4*1)^2 = 16. So, B is also not right
For D:
g(1) = 4(1)^2 =4. Point (1,4) that's show on the graph works for this equation.
D is correct
