Question 4. Just replace x with 2a.
So f(2a) = 5(2a)^2 + 4(2a)
= 5*4a^2 + 8a
= 20a^2 + 8a
Question 5. Since x = 3, which is more than 1, use the second equation.
f(3) = 3^2 + 1
= 9 + 1
= 10
Answer:
I think the answer is 7.5
Step-by-step explanation:
If y=f(x)
Domains are input or plug in value of x which we put in equation for a variable accordingly we get output or y's values which is called range.
Here in the fig. clearly shown g(4)=5
Anwser is B.
I would draw a trapezoid.
Trapezoids are quadrilaterals with one pair of parallel lines, not two. A rectangle has two pairs of parallel lines and is congruent. Therefore, it is not a rectangle.
