Question 844159: If (4, b) is a point on the graph of y = 3x2 + 4x, what is b?
Answer by algebrahouse.com(1659) (Show Source): You can put this solution on YOUR website!
y = 3x² + 4x
(4,b) is a point
b = 3(4)² + 4(4) {substituted 4 for x and b for y}
b = 3(16) + 16 {evaluated exponent and multiplied 4 by 4}
b = 48 + 16 {multiplied 3 by 16}
b = 64 {added}
