limit as x approaches 3 of 5x^2-9x+7

x \to 3 lim (5 x^{2} - 9 x + 7)

25

Solution steps

x \to 3 lim (5 x^{2} - 9 x + 7)

Plug in the value

x = 3

= 5 \cdot 3^{2} - 9 \cdot 3 + 7

Simplify

5 \cdot 3^{2} - 9 \cdot 3 + 7 : 25

= 25

f (x) = x + 6

\int \frac{1}{81 e ^{- 9 x} + e ^{9 x}} d x

\int_{- 2}^{3} \frac{29}{x ^{4}} d x

sin^{2} (3 - 6 x)

n = 1 \sum \infty \frac{n !}{4 ^{n}}
