Which is the graph of the function f() = x2 + 2x - 6?

Alecsey [184]

The x-intercepts from the graph are -3.646 and 1.646 with the <u>parabolic curve facing upwards</u>

<u />

<h3>Quadratic graph</h3>

Quadratic functions are functions that has a leading coefficient of 2.

According to the question, we are to graph the quadratic function f(x) = x^2 + 2x - 6. The curve will be parabolic in nature and facing upwards since it is a quadratic function.

The x-intercepts from the graph are -3.646 and 1.646 as shown in the attached graph.

Can you solve this? Show work

Dominik [7]

0.2÷ 1 then × both by 100 to change it to 20/100 then simplify by ÷5 which equals 4/20.
31. 4/20 to 1/5

0.24 × 100= 24
1×100 = 100
simplify 24 ÷ 4= 6 then 100÷4= 25
34. 6/25

-0.1 ×100= -10
1×100=. 100
simplify -10÷2=-5 then 100÷ 2= 50
32. -5/50 to -1/10

Just do that for 33, 35 and 36
