limit as x approaches 4 of 4x^2-5x+1

x \to 4 lim (4 x^{2} - 5 x + 1)

45

Solution steps

x \to 4 lim (4 x^{2} - 5 x + 1)

Plug in the value

x = 4

= 4 \cdot 4^{2} - 5 \cdot 4 + 1

Simplify

4 \cdot 4^{2} - 5 \cdot 4 + 1 : 45

= 45

ln (x + 3)

2 x^{2} + 7

y^{^{'}} - 2 y = - 1, y (0) = 3

(y - x) e^{x} + (1 + e^{x}) y^{^{'}} = 0

10 + \frac{50 t}{2 t ^{2} + 9}
