1 answer:

3 0

X-intercept: y = 0
y-intercept: x = 0

3x + 4y = 0

x-intercept: subtitute y = 0
3x + 4 · 0 = 0
3x = 0
x = 0 → (0; 0)

y-intercept: subtitute x = 0
3 · 0 + 4y = 0
4y = 0
y = 0 → (0; 0)

F(x) = 30.eˣ
We notice that the graph intercept y-axis at 30
in f(x) = 30.eˣ , for x=0, e⁰ =1 and f(x) = 30
In short it's the only function that has a y-intercept = 30 (answer B)

The function a(1) =1/2I^2 describes the area of an isosceles right triangle with leg I. Make a table of values for I=1,2,3 and 4

prohojiy [21]

Functions can be represented using equations, graphs and tables.

The function is given as:

$a(l) = \frac 12 l^2$
