Which quadratic function shows a y-intercept of 4 and a maximum value of 5
Elena L [17]

Answer:

The 4th graph

Step-by-step explanation:

To have a maximum value, your parabola would have to open downwards. So the first 2 are wrong. Since your y-intercept is positive 4, your graph would have to touch the y axis at 4. The 3rd graph is wrong since it touches the y-axis at a negative point. The correct answer would be the 4th answer choice.

What is the answer I've been trying for three hrs my teacher said to look it up so plz help
marin [14]
There are four s's and two sevens. Two times seven is fourteen and four times s is 4s. So then you have 4s + 14. Subtract 14 from 114 and then divide the quotient by 4. This should get you 25. so then every side is 25, and for the length it's 32 because s=25 and the equation you have says s+7. The dimensions would be 25 plus 25 plus 32 plus 32
