257 Построить график функции: 1) y = 3* - 1; 2) y = 3* -1; 3) y = 22-*+3.

Построить график функции:

1) y = 3x - 1;

<canvas id="myChart5" width="400" height="400"></canvas>
<script>
var ctx = document.getElementById('myChart5').getContext('2d');
var myChart = new Chart(ctx, {
    type: 'line',
    data: {
        labels: [-3, -2, -1, 0, 1, 2, 3],
        datasets: [{
            label: 'y = 3*x - 1',
            data: [-10, -7, -4, -1, 2, 5, 8],
            borderColor: 'blue',
            borderWidth: 1,
            fill: false
        }]
    },
    options: {
        scales: {
            y: {
                beginAtZero: true
            }
        }
    }
});
</script>

2) y = 3x -1;

<canvas id="myChart6" width="400" height="400"></canvas>
<script>
var ctx = document.getElementById('myChart6').getContext('2d');
var myChart = new Chart(ctx, {
    type: 'line',
    data: {
        labels: [-3, -2, -1, 0, 1, 2, 3],
        datasets: [{
            label: 'y = 3^x - 1',
            data: [0.037-1, 0.11-1, 0.33-1, 1-1, 3-1, 9-1, 27-1],
            borderColor: 'blue',
            borderWidth: 1,
            fill: false
        }]
    },
    options: {
        scales: {
            y: {
                beginAtZero: true
            }
        }
    }
});
</script>

3) y = 22-x+3.

<canvas id="myChart7" width="400" height="400"></canvas>
<script>
var ctx = document.getElementById('myChart7').getContext('2d');
var myChart = new Chart(ctx, {
    type: 'line',
    data: {
        labels: [-3, -2, -1, 0, 1, 2, 3],
        datasets: [{
            label: 'y = 2^(2-x)+3',
            data: [2^(2+3)+3, 2^(2+2)+3, 2^(2+1)+3, 2^(2-0)+3, 2^(2-1)+3, 2^(2-2)+3, 2^(2-3)+3],
            borderColor: 'blue',
            borderWidth: 1,
            fill: false
        }]
    },
    options: {
        scales: {
            y: {
                beginAtZero: true
            }
        }
    }
});
</script>
