Evaluate Using the Given Value f(1)=-0.7(1)^2+2.3(1)+5.4

$f (1) = - 0.7 {(1)}^{2} + 2.3 (1) + 5.4$

Step 1

Simplify each term.

One to any power is one.

$f (1) = - 0.7 \cdot 1 + 2.3 (1) + 5.4$

Multiply $- 0.7$ by $1$ .

$f (1) = - 0.7 + 2.3 (1) + 5.4$

Multiply $2.3$ by $1$ .

$f (1) = - 0.7 + 2.3 + 5.4$

Step 2

Simplify by adding numbers.

Add $- 0.7$ and $2.3$ .

$f (1) = 1.6 + 5.4$

Add $1.6$ and $5.4$ .

$f (1) = 7$
