Graph the parabola.
Y = 4x^2 + 7

In Picture Below:

Step-by-step explanation:

To graph:

1. find the y intercept of the equation (y=4x^2+7, let x =0, y=4*0 +7 which equals y=7)

2. find the x intercepts (if there are any); y=4x^2+7, let y =0, 0=4x^2+7, 4x^2=-7, therefore no x intercepts (you cannot root a negative)

3. find vertex using -b/2a formula, a=4 b=0 c=7, therefore x =0, sub that into y=4x^2+7, y=7, therefore vertex is (0,7)

4. graph all this information

step-by-step explanation:

*calories burned = (weight)(calorie factor)*

calories burned = 180 (0.65)

calories burned = 117

the calories he used up is 117, which is 65% of his weight.
